We now check the list of CVars to see if there's any unregistered CVars specified (i.e. in config, but not actually registered by the code). This would probably indicate a typo.
Only doing this on the server for now. The client may share config files from multiple codebases and end up with unknown CVars from there. This is probably fine, since those would be applied more automatically and not prone to config file typos as much.
* 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.
