Large sections of game logic are now working through libgdx instead of android libraries. There is still work to do but this is the first major step. Big changes include: - Graphics code is now through LibGDX (except for text rendering) - Initialization and screen-handling logic is now mostly through LibGDX - Audio is now through LibGDX - Input handling is now through LibGDX - Most misc functions are now through LibGDX
