Fixed storyboard conflicts
added the content for the credits, finished feature
Added alpha to the Music and SFX buttons so they look "off" when they are turned off.
Tweaked parameters of bounce mini game. I decided to keep the penalty for putting a bad ball in the good bucket the same as the penalty for putting a good ball in the bad bucket so the scoring system is easy for the player to understand.
Added sound effects for bounce, correct sort, and incorrect sort. Implemented the playing of the latter two sounds, but not bounce.
