Tactical Combat AI

[BetaSpectre]

Raiders really do need better AI.
And fewer numbers all in all.

But colonist AI IMO should be micro managed. They're colonists not Mercenaries.

Pawn AI should be determined by skill, and job. Instead of arbitrarily assigned as expert or horrible. And if Colonist AI were perfect what's the point of me?

A gardener will shoot the first thing that has spikes and screams. A merc might take out the teddy bear with the rocket or sniper first.
