Unique Melee grips#828

I think it would be a good idea if we had some unique grips for melee weapons, like a two-handed sword grip (for greatswords like a zweihander) or one-handed polearm grips (so for things like spear use with a shield, if we want to make a hoplite or Spartan themed mech).

two-handed sword weapon grips already confirmed for the future, and I believe you can technically do spear and shield already can you not?
