Saturation

I made it so it should remove from saturation before removing from foodLevel. I think it's just a really simple thing of basically removing from saturation first if we can, then removing from foodLevel. So I haven't really tested it at all. That, plus this is the first time I've done anything with CraftBukkit plugins, and wasn't sure how to go about setting up an eclipse project, make the jar, testing on my server, blah, blah, all with a plugin that already existed and wasn't created fresh in eclipse.

I didn't even think about making it optional in the config until just now, but seeing as this should now mirror the default hunger mechanics, I wouldn't think anybody would want it as optional.
