training maps

first 4 levels of the training maps are live
  this is very much a work in progress, but I'm putting it up for feedback

stunned and frozen mobs do no harm by default
  removed tech: osmoprotectant - stunned and frozen mobs do no harm

tech: annelids - randomly increase worm size and damage up to 100%

weak anthropic principle gives 45->50% duplication chance after almost dieing
complex spin-statistics immune to harm for 1.5->1.8 s every 7 s
exciton gives 60->66% damage
electronegativity gives 1% dmg for every 11->10 stored energy
arsenal gives 14->12% more damage per gun
pair production is now also a standing wave field tech
mass-energy takes 10% less damage
JUNK tech black hole cluster spawns mobs farther away, so you have a better chance to survive
undefinded tech no longer shows up on your first couple times playing, since it's a distraction for new players
