more orbs in text

replaced tech, field, and gun text with orbs
  orbs length scale with px->em
cleaned up simulation variables text in pause menu
some minor tech description changes
total tech count no longer includes instant tech or removed tech

tech: planned obsolescence - at the start of each level eject your oldest tech and gain 1.1 damage

heuristics 1.3 -> between 1 and 1.5 fire rate
combinatorial optimization 1.35->1.4 damage

difficulty reduction per level
  0.85->0.87x damage done
  1.23->1.22 damage taken
