Added the Staff of Change gun, a self recharging weapon which cannot be placed in a recharger. It fires bolts of change

Added a new projectile "bolt of change."
When struck by a bolt of change, a mob will be randomly transformed into one of the following:
-Alien (Drone/Sentinel/Hunter)
-Metroid (Adult/Baby)
-Cyborg
-Monkey

The staff is admin only as of now.

Fixed some bits on the salvage shuttle.
