Attempts to eliminate any confusion between OsuHitObject (raw, parsed hit objects) and HitObject (interface for game object types).
- Renamed "HitObject" interface to "GameObject", since these objects are specific to gameplay.

Error handling (related to #53):
- Catch all exceptions caused by creating HitObjects and throw a more informative error with the hit object information. This also allows multiple errors to be reported, instead of crashing at the first error.
- Added a fallback "DummyObject" HitObject to replace hit objects causing errors, which should allow the game to function despite any errors.
- Added a toString() method to OsuHitObject (resembling the raw format).
Bug fixes (caused by #52):
- Game is no longer paused when focus is lost during lead-in time or during breaks.
