Some of the basic functionality for the entity proxy.
Updated the WorldProxy class so it handles the transform serialization.
Compile fixes for last commit.
Renamed "PhysicsProxy" to "CollidableProxy", to help make it more descriptive and also not have to use the name of the namespace in it's own name.
Moved the SceneManager class to the Graphics namespace.
Updates to script bindings.
