TakeDamage
The damage is coming from inflictor, but get mad at attacker
This should be the only function that ever reduces health.
bitsDamageType indicates the type of damage sustained, ie: DMG_SHOCK
Time-based damage: only occurs while the monster is within the trigger_hurt.
When a monster is poisoned via an arrow etc it takes all the poison damage at once.
