merged shotgun tech

railgun and foam have a bit more ammo
capacitor bank makes foam gun fire a stream of foam
tech shift registers is now always on
  (set ON/OFF to ON at the start of a new level)
tech from applied science doesn't count for various tech that convert tech into other things (pure science, many worlds)
grappling hook now shows hooks on the grapple

merged similar gun tech
  needle gun+needle shot
  rivet gun+shotgun slug
  shockwave+blast mines
  nematodes+worm-shot
  necrophoresis+necrophage
    the worm aspect now spawns 3 copies instead of just a lifespan reset

-grapple goes 40% farther before it retracts automatically
-grapple now works well with fire delay reduction
-  or it's annoying, you decide!
-smelting cost more ammo as you increase stacks

-grappling hook tech: bulk modulus - immune to harm while grappling, but drain a bit of energy

-particle collider renamed pure science - and it gives 1 research instead of energy when it fails: 4% chance
