Adds a Rocky Diet

Taking the ore eater trait, you only gain nutrition from ore.
The amount varies, mainly based on the rarity/quality of what you're eating.

5 raw diamonds or verdantium will feed you well, while it'll take a handful of hematite or carbon to do the job. Better stick to the good stuff - it's in your best interest!
