New minimum levels for units, useful for trigger/decoy

the lower the level the less damage it will inflict.  as a decoy that is great. i have achieved it by finding a way to damage my unit on a camp 1st and do not let it heal. the damaged troop does less damage. seems as if at half health it does the damage of unit half its level. it is a pain to do it and maintain, but it does the trick when necessary
