rework materials from the ground up

[Nnystyxx]

I like the ideas recently proposed: chemicals doing something new and interesting rather than "smack a man he die", and materials actually having unique and interesting effects. Material science was, before it was gutted, essentially slightly different versions of the same things and uqill armor all the time farty party. Actual benefits and drawbacks and some situational use to the various materials could really afford some interesting ways to shake up the game formula.

Also different materials/minerals might be an excuse to make mining more fun.
