Suggestion: Make use of copper

[MuteTiefling]

Going back through recipes, I'm remembering how Iron heavy this mod can be. It would be nice to have some recipes adjusted to make use of Copper instead.

This would naturally involve a new crystal form of Copper. I'm proposing Crepporium or Croppentine to keep with the theme of slightly modified anagrams the mod already uses.

This could then be used in place of Enori in a few early recipes, such as generators and the farmer.
