BallShoot - A bare bones shooter game easy to expand on.

@SierraKen:  I haven't duplicated that error yet, but will keep testing for it.   I added a special kamikaze ball that seeks the player out and is faster.  Gonna add a few more things before posting a new version though, maybe clean up the code.   May use different ball types - the one ball is getting boring.
