bulk modulus

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
