Matt Leja adds some cheese

Hello everyone! Today I pushed some code that finally gave the game some power-ups, which right now just add points to the mouse. As of now the only power up is cheese and there is as many pieces as the level number. So, level 5 has 5 pieces of cheese randomly placed on the map. The cheese will be removed from the map, and be removed from the array it was in.

Next may be adding other power-ups, garbage and bread are in the works and once I have copy write free images, they should be implemented pretty soon.

Also, we are going to add a page after each level, which may display the number of power ups as well as maybe the images of them in a group.
