This is a gigantic kerfuffle because Chromium expects a very specific directory & app bundle layout. Have to change a bunch of resource loading code to account for content development being launched from an app bundle, and also had to make automatic MSBuild tooling & a python script to generate such an app bundle
* 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.
* Removed the Interfaces folder.
* All objects inside the GameObjects subfolders are now in the GameObjects namespace.
* Added a Resharper DotSettings file to mark the GameObjects subfolders as not providing namespaces.
* Simplified Robust.client.Graphics namespace.
* Automated remove redundant using statements.
