Combat Reactions

Each friendly being has one of the following Combat Reactions:
- Free Will: The being will fight while it holds a weapon it can use and is not badly hurt, and flee otherwise.
- Fight: The being will shoot enemies it can hit from where it stands, or go at enemies close by with a melee weapon, then go back to work. Draft it to send it into the fight.
- Flee: The being will run away from enemies close by, and work otherwise.
- Ignore: The being will focus on colony tasks and personal needs, ignoring enemies unless provoked or given a Direct Order.
