catabolism and inductive coupling update

catabolism - lowers your max health by 1 (was 3 harm) and gives 4 ammo
inductive coupling - gives max energy for leftover power ups (was max health)
  now requires mass-energy equivalence

switched to a newer copy, paste URL
  this seems to fix issues with failed text copy in the level builder if you hold mouse down for over 6 seconds
