Can now score and ball bounces off walls

Need to make the paddles move and the ball to bounce of paddles. I've got
maybe 1 hour in me tops, left. This will be tricky.

TODO:

Paddle control                    2hrs
- Key input system                1hrs
Paddle ball bounce                1hrs
Store the game data to the server 2hrs

Make pretty.                      3hrs

16hours left in about 30 hours of time. It shouldn't take me like half the
time to do most of those things, but I want to stay safe with my time. I
think I might just try to stick with local MP, just for the sake of time.
