Added a Thumbnail and Icon for the game,  which may be changed later,  but I don't think theres too big of a problem with them.  They are intended to be pixelated.  You can pull request if you design a better one and I will credit you if I use it.

I also added a test class that will be removed later named MouseBullet which is a "bullet" that follows the mouse.  It registers itself with the LogicEngine and GraphicsEngine.  I also added a FPS counter at the title of the window.
