Players are no longer knocked back from downed players
Downed players are now able to change their Y coordinate
Removed the barrier block that keeps the player in a "swimming" state. This now uses an event to keep them down (coding term don't worry about it)
This has the effect of the downed player not being on the floor in their POV. The downed player still appears to be down for other players. I will attempt to fix this in a future update
Plugin armour stands are now unable to steal items off players
