iron man mode: cowards prestige

[bearded]

i'm thinking it would work this way;  when a monster is spawned, there is a variable based on it's prestige stored.  when the monster is killed, the variable is awarded as prestige, and subtracted from the variable prestige. 
when the mission is loaded, the prestige variable is subtracted from the mission prestige.
this way, you would get fewer prestige points for finishing a mission, the more times you restart the mission.
