Inline Mouse Over effect

[namoricoo]

/* I added a couple of functions for the mouse over effect. So if you have a 3 state button like, var playButton = UIButton.create( "playUp.png","playOver.png", "playDown.png", 0, 0 ); This will work work correctly without having to do the current hack that's in the Kitchen sink tutorial.
