grappling hook
  tech: reel - increase block damage 400%, generate 30 energy after hooking blocks
  added tokamak to grappling hook
  updated rope graphics
  added input.up to adjust positioning while hook is attached
  added images for CIWS, rupture, autonomous defense
  aerostat: 25->15% reduced damage on ground
  rupture unlocks explosive tech
  rupture destroys blocks
  autonomous defense renamed to CIWS

field emitter 6->4 base energy regen
tech: autonomous defense - harpoon tech that fires harpoons after taking damage
degenerate matter: 75->85% defense while field is active
neutronium: 90->95% defense while field is active
unified field theory no longer has field emitter as an option
