spider boss

large mods shrink on death instead of disappearing
new boss mob:  spiderBoss
mod - Bayesian interference -> determinism
   spawn 4 mods and 2 heals, future power ups are limited to one choice
mod - Leveraged investments -> Bayesian interference
   33% chance for double power ups to drop, remove all future ammo power ups
(serious progress on my level construction tools, but it's not ready yet)
