Separate fight-or-flight into second behavior stage

[gilmore606]

remove behavior.ForF()
when behaviors want to signal ForF, they return a special faux ActionForF() to go into the urgency election
if this action is picked, a new round of behavior picking happens
behavior.actionForF() is polled, urgency + status calculated by each behavior, highest picked

[gilmore606]

SelfDefend.actionForF() -- check actor.confidence() (looks at wounds vs hubris), set urgency opposite to confidence, return a flee action -- lower confidence if adjacent, lower if target has missile, lower by distance. can be over 1f if confidence not berserker-level and wounds high

Hitter.actionForF() -- if no melee weapon, null. if in hit range of target, Attack 1f, or equip melee 0.8f. else step toward target, urgency opposite to distance

Shooter.actionForF() -- if no missile, null. if in optimal range, attack 1f, or equip missile 0.8f. if out of range, step toward, urgency opposite to distance-from-range.

[gilmore606]

make ActionGoal("string", targetentity) which triggers the re-election of behaviors to get a real action, by asking their doGoal()

give up on ForF -- just have selfDefend or whatever decide right there (via its own params like aggression) whether to fight or flight, and return ActionGoal("fight") or ActionGoal("flee")
