Material Rework PS1

This mod changes the stats of gold, iron, and enderite (if enderitemod is installed) tools and armor.

* Gold now has a mining level between iron and diamond 4.
* Iron is slightly weaker compared to vanilla and gold is buffed to be stronger than vanilla iron in both speed and durability.
* Turtle shell (and full turtle armor if installed) is significantly nerfed to around the stats of iron.

Various tools have been rebalanced.

Most of these stats can be configured except for mining levels, if you change any values the game must be restarted.
