Our first look at a block moving!

This code is not complete. I can get the East Block moving East, and only when I hit a special key. 

I also have the decision to make if I want the blocks to be simply labeled as a north/south/east/west block on every side, or have an arrow indicator on every side of the block that dictates the direction it will move. If the latter, I will have to dig into the renderer and figure out how to make each side render a different texture.
