Title: Use a globally accessible WitchBlastGame object

- Add game() function, which returns the
single instance of WitchBlastGame.

This way, we can avoid the inconvenience of having to pass
a WitchBlastGame reference to every object that wants to use it.

- Replace every WitchBlastGame reference with game().
