Implemented tutorial bubbles

GameLayer now has support for pausing game flow and displaying a tutorial bubble that the user can tap to dismiss. No code has been written, however, to make use of this, because I think it may be simpler to abstract GameLayer out somewhat and create a separate game mode for the tutorial. Deliberation required.

PauseLayer has also been removed and the behavior has been brought into GameLayer.
