Quick compatibility fix for PA Update 8a

- You can now sack the basketball. This comes in handy when you dismantle a court while a ball was left behind. For the blind inmates there is a staffkey inside the ball, so they can hear it when the ball comes towards their face.
-Scoreboard will now show the last 4 digits of the court it's connected to when clicking GAME ON.
- Minor bug fix on GAME OFF button, it would in some cases not turn the court in sleep mode.

- Added a dribble effect to the ball.
-Tweaked too many little things to mention to let the game run as smooth as possible.
-Added a variety of quickbuild rooms.
-Updated the whistle sounds.

-Added more floor types and set all types to fast.
-Fixed error about current player being nil after loading a saved game while a match was played.
-Fixed multiple balls on court.
-Adjusted the scanning range of the court.
-Added a Basketball Trainer.
-Added two new rooms.
-Added button to kill or delete the ball after a match: if you want a bloody match, the killed ball will be brought to a Basketball Locker, leaving some blood behind. No idea if this affects the death rate of the prison, feel free to test it out.

HOTFIX: a small script error would occur if you enable/disable the court lights before a game was ever played (since it wouldn't build a list of lights before a game would start)...

Initial release V2.0 with realtime basketball game.
