Paul Speed 3b8314a36f Part 1 of small refactoring to give AppState a unique ID for lookup purposes.
This is a breaking change for direct implementers of AppState as they must
add a getId() method.  (Which is also a good time to evaluate if they should
be extending AbstractAppState or BaseAppState and/or if their life cycle is
implemented correctly. e.g.: BulletAppState is breaking the AppState contract
a bit.)
