Get the ball rolling (Implement Ball Logic)

[j-jacobson]

Make it so the ball moves.
Ball should always start by heading towards one of the paddles (should be the loser? Look up the rules). It should begin when a button is pushed (center button for now.)
Every time it hits a paddle the speed should increase slightly. Every time it hits a wall it should slow down slightly.
Ball should reset position once it hits x=0 or x=h_Size.
