Adds mob forgiveness

Makes it so that if you rest while being attacked by a retaliate mob, they may decide to stop attacking you.

They will forgive you if their health is full, if they cannot eat you, and if they are otherwise not hostile. If they CAN eat you, then their behavior will be as normal, they will proceed to eat you.

At the moment this applies to all retaliate mobs, but a variable `forgive_resting` is in place for in case we want some mobs to not be so forgiving, be it normally or through adminbus.
