Set butchering ahead of cooking meals.

[BlackSmokeDMax]

I'd love to see butchering ahead of cooking meals. More likely to have meat ready to go to cook. This is much more important pre-electricity when you don't have coolers and want to make sure meat gets used ASAP.

Right now I get by with setting butchering higher than cooking meals, via the advanced mode of Fluffy's Work Tab mod, but it'd be nice to not need it for cooking. Plus once you start setting that ahead it causes a bit of a cascade of re-setting other priorities.

Now that we no longer need to "butcher forever" (the "do until you have..." now works correctly in vanilla), it makes more sense to have your butchering done before cooking.

Sorry if any of this is a bit illegible, I copy/pasted my request from fluffy's thread, and changed some of it. I should probably be doing this in the morning when I'm not dead tired and ready for bed. I'll likely expand or fix this tomorrow if it seems a bit gibberish. It looks good now, but I have that feeling something is off.
