[FEATURE] New food recipes/items

[Flourish]

Bee kibble, the birthday cupcake, and onion chips are sensible for To Serve Man... maybe tack the bee ones in their own little section at the end?

Butt-er I'm torn on. The book probably needs a bit of an overhaul to make it more usable anyway, so (to save me looking) if the recipe for mayonnaise is in there then put the recipe for butt-er in there for now, and I'll take a pass at it at some point. Ditto for pickles.

Also, just skimming the code for the birthday cupcake, I'm reasonably sure there's some screwiness around its specialOutput function, specifically reagents are added in both specialOutput and in New for the actual item?

Recipes have been added! The use of periods is a bit inconsistent - I was unsure which style to stick with.

Looking back, yeah, that was a dumb way to code it. I've simplified things.
