* Adds ServerOptions, improve GameControllerOptions, fix engine integration tests
* Do component auto-registration in engine integration tests by default
* Fix integration tests on content, register components ONLY if not contentstarted or options are null
* Add integration test for engine integration tests working correctly
* Move cvar overrides out of content and into engine.
This allows us to make Content.Client and Content.Server Exe projects so that they can be executed directly via your IDE. This'll help wtih not forgetting to do a full rebuild and such.
