Raise event when entity paused state changes.

FullState was getting updated before ResetPredictedEntities ran instead of after. So ResetPredictedEntities was applying data to stuff like containers that depends on entities that hadn't been made yet.

-				<h1>Peer/server discovery</h1>
-				<p>
-					Peer discovery is the process of clients detecting what servers are available. Discovery requests can be made in two ways; 
-					locally as a broadcast, which will send a signal to all peers on your subnet. Secondly you can contact an ip address directly 
-					and query it if a server is running.
-				</p>
-				<p>Responding to discovery requests are done in the same way regardless of how the request is made.</p>
-				
-				<p>Here's how to do on the client side; ie. the side which makes a request:</p>
-				<div class="cf">
-					<pre class="cl"><span class="cb1">// Enable DiscoveryResponse messages</span></pre>
-					<pre class="cl">config.EnableMessageType(<span class="cb2">NetIncomingMessageType</span>.DiscoveryResponse);</pre>
-					<pre class="cl">&nbsp;</pre>
-					<pre class="cl"><span class="cb1">// Emit a discovery signal</span></pre>
-					<pre class="cl">Client.DiscoverLocalPeers(14242);</pre>
-				</div>
-
-				<p>This will send a discovery signal to your subnet; Here's how to receive the signal on the server side, and send a response back to the client:</p>
-
-<div class="cf">
-<pre class="cl"><span class="cb1">// Enable DiscoveryRequest messages</span></pre>
-<pre class="cl">config.EnableMessageType(<span class="cb2">NetIncomingMessageType</span>.DiscoveryRequest);</pre>

-<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb3">case</span> <span class="cb2">NetIncomingMessageType</span>.DiscoveryRequest:</pre>
-<pre class="cl">&nbsp;</pre>
-<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb1">// Create a response and write some example data to it</span></pre>
-<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb2">NetOutgoingMessage</span> response = Server.CreateMessage();</pre>
-<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; response.Write(<span class="cb4">&quot;My server name&quot;</span>);</pre>
-<pre class="cl">&nbsp;</pre>
-<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb1">// Send the response to the sender of the request</span></pre>
-<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; Server.SendDiscoveryResponse(response, inc.SenderEndpoint);</pre>
-<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb3">break</span>;</pre>
-</div>
-
-<p>When the response then reaches the client, you can read the data you wrote on the server:</p>

-Improvements over last version of library:
-
-* New delivery type: Reliable sequenced (Lost packets are resent but late arrivals are dropped)
-* Disconnects and shutdown requests are now queued properly, so calling shutdown will still send any queued messages before shutting down
-* All messages are pooled/recycled for zero garbage
-* Reduced CPU usage and lower latencies (in the <1 ms range, but still) due to better socket polling
-* All public members of NetPeer/NetConnection are completely thread safe
-* Larger number of delivery channels
-* More exact roundtrip measurement
-* Method serialize entire objects via reflection
-* Unique identifier now exists for all peers/connections
-* More flexible peer discovery; filters possible and arbitrary data can be sent with response
-* Much better protection against malformed messages crashing the app
-
-API enhancements:
-* NetPeerConfiguration immutable properties now locked once NetPeer is initialized
-* Messages cannot be send twice by accident
-* Impossible to confuse sending and receiving buffers since they're different classes
-* No more confusion if user should create a buffer or preallocate and reuse

-					Lidgren basics</h1>
-				<p>
-					Lidgren network library is all about messages. There are two types of messages:</p>
-				<li>Library messages telling you things like a peer has connected or diagnostics messages (warnings, errors) when unexpected things happen.</li>
-				<li>Data messages which is data sent from a remote (connected or unconnected) peer.</li>
-				<p>
-					The base class for establishing connections, receiving and sending message are the NetPeer class. Using it you can make a peer-to-peer network, but if you are creating a server/client topology there are special classes called NetServer and NetClient. They inherit NetPeer but sets some defaults and includes some helper methods/properties.</p>
-				<p>
-					Here's how to set up a NetServer:</p>
-				<div class="cf">
-					<pre class="cl"><span class="cb2">NetPeerConfiguration</span> config = <span class="cb3">new</span> <span class="cb2">NetPeerConfiguration</span>(<span class="cb4">&quot;MyExampleName&quot;</span>);</pre>
-					<pre class="cl">config.Port = 14242;</pre>
-					<pre class="cl">&nbsp;</pre>
-					<pre class="cl"><span class="cb2">NetServer</span> server = <span class="cb3">new</span> <span class="cb2">NetServer</span>(config);</pre>
-					<pre class="cl">server.Start();</pre>
-				</div>
-				<p>
-					The code above first creates a configuration. It has lots of properties you can change, but the default values should be pretty good for most applications. The string you provide in the constructor (MyExampleName) is an identifier to distinquish it from other applications using the lidgren library. Just make sure you use the same string in both server and client - or you will be unable to communicate between them.</p>
-				<p>
-					Secondly we've set the local port the server should listen to. This is the port number we tell the client(s) what port number to connect to. The local port can be set for a client too, but it's not needed and not recommended.</p>
-				<p>
-					Thirdly we create our server object and fourth we Start() it. Starting the server will create a new network thread and bind to a socket and start listening for connections.</p>
-				<p>
-					Early on we spoke about messages; now is the time to start receiving and sending some. Here's a code snippet for receiving messages:</p>
-				<div class="cf">
-					<pre class="cl"><span class="cb2">NetIncomingMessage</span> msg;</pre>
-					<pre class="cl"><span class="cb3">while</span> ((msg = server.ReadMessage()) != <span class="cb3">null</span>)</pre>
-					<pre class="cl">{</pre>
-					<pre class="cl">&nbsp;&nbsp;&nbsp; <span class="cb3">switch</span> (msg.MessageType)</pre>
-					<pre class="cl">&nbsp;&nbsp;&nbsp; {</pre>
-					<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb3">case</span> <span class="cb2">NetIncomingMessageType</span>.VerboseDebugMessage:</pre>
-					<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb3">case</span> <span class="cb2">NetIncomingMessageType</span>.DebugMessage:</pre>
-					<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb3">case</span> <span class="cb2">NetIncomingMessageType</span>.WarningMessage:</pre>
-					<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb3">case</span> <span class="cb2">NetIncomingMessageType</span>.ErrorMessage:</pre>
-					<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb2">Console</span>.WriteLine(msg.ReadString());</pre>
-					<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb3">break</span>;</pre>
-					<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb3">default</span>:</pre>
-					<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb2">Console</span>.WriteLine(<span class="cb4">&quot;Unhandled type: &quot;</span> + msg.MessageType);</pre>
-					<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb3">break</span>;</pre>
-					<pre class="cl">&nbsp;&nbsp;&nbsp; }</pre>
-					<pre class="cl">&nbsp;&nbsp;&nbsp; server.Recycle(msg);</pre>
-					<pre class="cl">}</pre>
-				</div>
-				<p>
-					So, lets dissect the above code. First we declare a NetIncomingMessage, which is the type of incoming messages. Then we read a message and handles it, looping back as long as there are messages to fetch. For each message we find, we switch on sometime called MessageType - it's a description what the message contains. In this code example we only catch messages of type VerboseDebugMessage, DebugMessage, WarningMessage and ErrorMessage. All those four types are emitted by the library to inform about various events. They all contains a single string, so we use the method ReadString() to extract a copy of that string and print it in the console.</p>
-				<p>
-					Reading data will increment the internal message pointer so you can read subsequent data using the Read*() methods.</p>
-				<p>
-					For all other message type we just print that it's currently unhandled.</p>
-				<p>
-					Finally, we recycle the message after we're done with it - this will enable the library to reuse the object and create less garbage.</p>
-				<p>
-					Sending messages are even easier:</p>
-				<div class="cf">
-					<pre class="cl"><span class="cb2">NetOutgoingMessage</span> sendMsg = server.CreateMessage();</pre>
-					<pre class="cl">sendMsg.Write(<span class="cb4">&quot;Hello&quot;</span>);</pre>
-					<pre class="cl">sendMsg.Write(42);</pre>
-					<pre class="cl">&nbsp;</pre>
-					<pre class="cl">server.SendMessage(sendMsg, recipient, <span class="cb2">NetDeliveryMethod</span>.ReliableOrdered);</pre>
-				</div>
-				<p>
-					The above code first creates a new message, or uses a recycled message, which is why it's not possible to just create a message using new(). It then writes a string ("Hello") and an integer (System.Int32, 4 bytes in size) to the message.</p>
-				<p>
-					Then the message is sent using the SendMessage() method. The first argument is the message to send, the second argument is the recipient connection - which we'll not go into detail about just yet - and the third argument are HOW to deliver the message, or rather how to behave if network conditions are bad and a packet gets lost, duplicated or reordered.</p>
-				<p>
-					There are five delivery methods available:</p>
-				<div class="cf">
-					<table>
-						<tr>
-							<td valign="top">
-								<b>Unreliable</b>
-							</td>
-							<td>
-								&nbsp;
-							</td>
-							<td valign="top">
-								This is just UDP. Messages can be lost, received more than once and messages sent after other messages may be received before them.
-							</td>
-						</tr>
-						<tr>
-							<td colspan="3">
-								&nbsp;
-							</td>
-						</tr>
-						<tr>
-							<td valign="top">
-								<b>UnreliableSequenced</b>
-							</td>
-							<td>
-								&nbsp;
-							</td>
-							<td valign="top">
-								Using this delivery method messages can still be lost; but you're protected against duplicated messages and if a message arrives late; that is, if a message sent after this one has already been received - it will be dropped. This means you will never receive "older" data than what you already have received.
-							</td>
-						</tr>
-						<tr>
-							<td colspan="3">
-								&nbsp;
-							</td>
-						</tr>
-						<tr>
-							<td valign="top">
-								<b>ReliableUnordered</b>
-							</td>
-							<td>
-								&nbsp;
-							</td>
-							<td valign="top">
-								This delivery method ensures that every message sent will be received eventually. It does not however guarantee what order they will be received; late messages may be delivered before older ones.
-							</td>
-						</tr>
-						<tr>
-							<td colspan="3">
-								&nbsp;
-							</td>
-						</tr>
-						<tr>
-							<td valign="top">
-								<b>ReliableSequenced</b>
-							</td>
-							<td>
-								&nbsp;
-							</td>
-							<td valign="top">
-								This delivery method is similar to UnreliableSequenced; except that is guarantees that SOME messages will be received - if you only send one message - it will be received. If you sent two messages quickly, and they get reordered in transit, only the newest message will be received - but at least ONE of them will be received guaranteed.
-							</td>
-						</tr>
-						<tr>
-							<td colspan="3">
-								&nbsp;
-							</td>
-						</tr>
-						<tr>
-							<td valign="top"><b>ReliableOrdered</b></td>
-							<td>&nbsp;</td>
-							<td valign="top">
-								This delivery method guarantees that messages will always be received in the exact order they were sent.
-							</td>
-						</tr>
-					</table>
-				</div>
-				<p>
-					Here's how to read and decode the message above:</p>
-				<div class="cf">
-					<pre class="cl"><span class="cb2">NetIncomingMessage</span> incMsg = server.ReadMessage();</pre>
-					<pre class="cl"><span class="cb3">string</span> str = incMsg.ReadString();</pre>
-					<pre class="cl"><span class="cb3">int</span> a = incMsg.ReadInt32();</pre>

-	/// A fast random number generator for .NET
-	/// Colin Green, January 2005
-	/// </summary>
-	/// September 4th 2005
-	///	 Added NextBytesUnsafe() - commented out by default.
-	///	 Fixed bug in Reinitialise() - y,z and w variables were not being reset.
-	/// 
-	/// Key points:
-	///  1) Based on a simple and fast xor-shift pseudo random number generator (RNG) specified in: 
-	///  Marsaglia, George. (2003). Xorshift RNGs.
-	///  http://www.jstatsoft.org/v08/i14/xorshift.pdf
-	///  
-	///  This particular implementation of xorshift has a period of 2^128-1. See the above paper to see
-	///  how this can be easily extened if you need a longer period. At the time of writing I could find no 
-	///  information on the period of System.Random for comparison.
-	/// 
-	///  2) Faster than System.Random. Up to 8x faster, depending on which methods are called.
-	/// 
-	///  3) Direct replacement for System.Random. This class implements all of the methods that System.Random 
-	///  does plus some additional methods. The like named methods are functionally equivalent.
-	///  
-	///  4) Allows fast re-initialisation with a seed, unlike System.Random which accepts a seed at construction
-	///  time which then executes a relatively expensive initialisation routine. This provides a vast speed improvement
-	///  if you need to reset the pseudo-random number sequence many times, e.g. if you want to re-generate the same
-	///  sequence many times. An alternative might be to cache random numbers in an array, but that approach is limited
-	///  by memory capacity and the fact that you may also want a large number of different sequences cached. Each sequence
-	///  can each be represented by a single seed value (int) when using FastRandom.
-	///  
-	///  Notes.
-	///  A further performance improvement can be obtained by declaring local variables as static, thus avoiding 
-	///  re-allocation of variables on each call. However care should be taken if multiple instances of
-	///  FastRandom are in use or if being used in a multi-threaded environment.
