+ Reworked how charm behaves.
+ When a mob is charmed, it should attack other mobs, and ignore players.
+ Charmed mobs cannot damage players.
+ Charmed mobs consider other mobs enemies and vice-versa.
+ Players can target and damage charmed mobs, and they won't fight back until uncharmed.
+ When a large cryoworm dies while charmed, the small worms shouldn't end up invulnerable.
+ If a mob is charmed with no other mobs around, it should no longer leash and heal itself.
