ICS Game Progress Day #4

Today, I made the program run more smoothly. Tried to fix the collisions with the top, right and left side of the screen, but only got the ball to bounce of the top and bottom of the screen. Also fixed the direction that the ball bounces. The paddle moves perfectly and I am happy with it. the only thing to do now is to make it stop when it hits x=0 and when x=maxx.
