Little fixes:

- Fixed the BeeTest sometimes-failure. Basically, sometimes the bee
would not move when we called update, so the imageNumber would not
change. This made tests fail. Fixed by adding a bunch of updates for
each part of the test; Since Bug.move now doesn't send Bees in random
directions, this will only fail about once per universe lifetime.
- Added a second GameBoard constructor that allows us to not play music
in tests. if you use GameBoard() it acts normally, but GameBoard(false)
now won't start the music... At least at the start of the game.
- I accidently hit crtl+shift+f on some other files, so this commit
includes so formatting changes.
