0.2.3

Scrapped everything, fuck that shit.

StateManager controls game state now, SwitchState(string) switches to a
menu state, and LoadLevel(int) loads a level at a given index. This
works by clearing all the children under Game and instantiating prefabs
stored in a set of GameObjects and an array of level GameObjects on the
StateManager script on Game. Anyways, to work on anything related to a
level scene, drag it under game, edit it, apply it to the prefab, then
remove it from the scene. Whatever you put in the scene under game will
just get deleted when play starts anyways so it doesn’t really matter
but in theory it makes the scene file smaller.
