Adds craftable Copper Armor and Copper tools, along with a custom Copper Trident!

The recipes are automatically unlocked upon collecting a Copper Ingot. Copper Armor grants the same defense as Chainmail Armor, at the cost of having less durability, but also granting a speed bonus per piece worn.

The Trident takes oxidized copper blocks, so you won't be able to craft it right off the bat!
