New gem types.

With the advent of Spell casting and a new sink for reagents. I think there should be reagent gems that could be gemcrafted. This is for people that either can't or don't want to pay through the nose for reagents. Also as an additional idea. Exp bonus gems, which would grants a % bonus per gem. I think this could be balanced out easily enough since you would lose out on fighting stats for bosses but pure battling would show faster rate of levelling.
