Dependency injection

[devo1929]

This adds dependency injection for all services (or service-like classes) AND all XNAControl based controls. The class ClientGUICreator was re-purposed to facilitate this dependency injection for all XNAControl based controls. They can be instantiated as a part of dependency injection in a constructor or when instantiated via an INI file. Controls are simply registered in a different way, but the backing logic mostly remains intact.

Sounds good. I don't have questions now and let's wait for others' reviews
