Fixed some nasty bugs, download again

Sorry!, fixed some nasty bugs, please re download again:

fixed:

• window doesnt close on pressing escape key anymore, asks for confirmation and only on main screen
• paddle not moving when some of the 3 balls went out of screen (triple ball powerup), same thing happened with the sticky powerup
• you can now move with arrow keys as well
• bug where the ball passed through the paddle when it was large
• highscore doesnt reset on game screen exit
