v0.2.1 - Window Scaling

Minor update to allow the AI to function again

Pretty much everything in this update addresses the for the game to function at any display size

-Updated Player.java to now draw the size and position based on the size of the screen
-Updated edge-of-screen collision to detect a change in screen size
    -The ball will now always completely disappear past the left/right before a score is registered
-Updated Ball.java
    -The ball(and paddle) reset mechanics to allow for scaling screen size
    -The ball will now draw its size that will scales with the screen size
    -Ball speed is now relative to the screen size.  This should mean the ball will move across the game screen at the same rate
-Updated ScreenFade.java to allow for a delay for easier fade outs handled by the object itself
-AI now reacts correctly with respect to screen size
