Columbo Buffs (#20151)

Removes the confusingly unnecessary nerf to Columbo's damage (he did as
much as just punching someone) from the parent mob and increases his
health from 75 to 125 so he can withstand at least a little more
punishment.

The poor guy is quite literally never let out of his enclosure because
he's less useful than just throwing a floor tile at someone. He's also
the only "unique" thing the Head of Security has left, and people seem
warm to the idea of an actual incentive to bring him out more. With
these buffs he stands an actual chance of being able to fight and take
down someone unarmed and unarmored.
