Whack A food - with bonus and mods.

Whack A food - with bonus and mods. Standard game, then added the 60 second timer bonus that ends the game. Also added the self guided extras; 3 lives before game ends, music with volume slider on intro screen, and game pause via the P key. Tweaked the difficulty levels with a float and changed the background and borders. Added a script on the background that'll spin and scale the background back and forth, faster for each difficulty.
