harpoon tech

harpoon gun
  shaped more like a harpoon
  grabs power ups slower, and from the tip of the harpoon
  only uses energy on returning
  doesn't have thrust if there is no mob target

  tech: reticulum - make one more harpoon if there are mobs nearby that you are facing
    I'm letting this stack to 9 even though it's silly cause that is n-gon's style
  tech: ceramics now lets both harpoons and needles ignore shields
    this was coded poorly so if shield bugs show up it might be from this
  tech: fragmentation makes ~15% fewer nails for everything it affects
  tech: filament gives 3% length per ammo (was 1%)
    also length is capped at 75 ammo because after that it's just annoying
  tech: unaaq is longer at low ammo but scales slower at high ammo

bugs
  fixed laser collisions on player head when crouching
  returned experiment gun and field circles
