abiogenesis

tech: abiogenesis - spawn a second level boss on each level, but costs 5 research or if you don't have the research add 49 JUNK tech to the pool
  note to level builders I rewrote the add duplicate boss code in all levels: spawn.secondaryBossChance(x,y)

foam tech: uncertainty principle - foam bullets change position randomly, increase foam damage by 66%

throwing blocks now charges faster with reduced fire cooldown
tech renormalization now has a 40% chance to refund a research  (was 37%)
performance- now precalculate player gradient fill
