Add Golem support gem

I heard this suggestion in chat yesterday, and it sounds great. The golem itself could follow a white weapon type for progression damage.

Start with the generic damage of shore weapons, and end with an average white merciless weapon. (Sorry I don't remember the actual item names, but you get the point).

This would be sort of like a totem for melee gems. :)

Linking this with leap slam would be the melee equivalent of lightning warp totems. ^^
