gauge threat when room is attacked

[pguth66]

based on something like total ATTACK parts of hostile creeps, or total parts of hostile creeps or something

• don't spawn a warrior when there's no real threat
• spawn big warrior when needed
• boost when needed
• multiple defenders when needed
• ranged only when not in reach of ramparts? (requires knowing where they are attacking)

should there be any logic for handling how many towers there are, or whether creeps are in range of towers?

things we need here

room.gaugeThreat() - returns some number like a defcon to say how bad things are and what action should be taken should be based on 1) strength of attacking force 2) how long they've been present? (maybe not needed right now) strength s/b # of attack + # of heal where boosted parts count as 2x or 3x or something

update to how warriors are spawned or maybe new room method way to make warriors of varying strengths based on 1) threat in room and 2) available energy
