* New HWID system prep
* Allow HWID to be disabled.
Both client and server can now request HWID to be disabled.
On the server via CVar, if disabled the client won't send it.
On the client via env var, if disabled it won't be sent to the client.
This involved moving legacy HWID to be sent in MsgEncryptionResponse instead of MsgLoginStart. This means the legacy HWID won't be available anymore if the connection isn't authenticated.
* Fix tests
* Fix another test
* Review
* Thanks Rider
* Renamed shared ICommand to IConsoleCommand.
* Lots of refactoring into a shared context.
* Removed ICommonSession from server concmd Execute.
* Added argStr parameter to concmd execute.
* The execute function of client concmds now returns void, use the new shell.RemoteExecuteCommand function to forward commands.
# Conflicts:
# Robust.Client/Console/Commands/Debug.cs
* Finally move shells and commands into shared.
* Console commands can now be registered directly without a class in a shared context.
* Pulled up ConsoleHost and Console shell into a shared context.
* Pulled up half the functions of ConsoleHost into a shared context.
* Repair rebase damage.
* Make LoadConsoleCommands function not remove any previously registered commands.
