chain reaction

tech: chain reaction now requires vacuum bomb, but it increases grenade radius and damage 33%
  (and makes blocks explode)

needle gun fires with more regular timing
needles despawn 1.5s faster, for performance reasons
intro level power ups are relocated
tech: decomposers renamed necrophage
if mobs are one shotted before they see you, they no longer alert nearby mobs
clicking on a mob in testing will log that mob in console
