Zoey's Rose Gold

Adds Rose Gold as a unique mix of Copper and Gold, allowing the creation of Rose Gold tools or upgrading gold items into Rose Gold via smithing table. 

Rose Gold is meant to allow gold to actually feel useful while keeping it as a sidegrade to Iron rather than a pure upgrade.

For example, the Rose Gold pickaxe has way more durability than Gold, but still less than Iron. It keeps the high speed of Gold, but it also keeps the terrible mining power preventing it from mining anything that would require a stone pickaxe or higher. This makes it a great excavation tool, but bad for caving, giving both Rose Gold and Iron pickaxes their own unique uses.

Rose Gold also has high enchantability just like Gold, but slightly less than it.
