NaN bug fix

generalist now requires 2 guns to unlock
  active cooling 18->20% fire speed increase per gun
  arsenal 12->13% damage increase per gun
futures exchange 4.3->4.5% duplication on cancel
perimeter defense 7->6% harm reduction per bot
unified field theory no longer gets bonus rerolls, instead it triples the frequency of field tech
  removed tensor field
meta-analysis gives 3->1 research after choosing JUNK

plasma ball moves faster 7->10

bug fixes
JUNK tech density removed
  it was causing the NaN bug
