Added scrolling to level selection screen

Using http://www.xcombinator.com/2010/09/08/a-paging-uiscrollview-in-cocos2d-with-previews/ as a base, I was able to implement a paging scroller for the level selection screen so players can swipe through available levels and choose one to play.

At this point, the level selection screen is practically done--the only other thing I want to add is a UIPageControl to interact with the scrolling and give the player an indication of how many levels there are.
