AntiBlock v3

• Swap with multiple players if there's enough room.
  • for when 2 players in front of you are trying to cram into a small doorway or vent.
• Kill rotating door blockers (ex: matmanizm2).
  • if the door does <10 damage then block damage will gradually increase as the door bounces back and forth, or if it's jammed. Block damage resets if the door isn't toggled for 1 second.
• Fix gibbing/sticking on elevators (ex: echoes13).
  • this happened when the swapper is crouching and the target is standing.
• Add swap sound
