Adds brewing ingredients, yeast, and sugar beet

Adds hops, barley, and molasses as brewing ingredients, yeast for
fermenting brews and baking some bread foods, and sugar beet as a
renewable source of sugar.
Adds fruit wine and brandy.
Adds mead, moonshine, homebrew beer

These don't spawn naturally.
Brewing prototype!

Very basic for now, fermenting is done instantly and only works with one
charge of ferment at a time. Under construction.
Working decanting, result_mult for recipes

Under construction
Craftable brews!
Fully working brewing!

It's finished. Works entirely as intended now. Also: alcohol_strong
Sticks brew_ items in trader_avoid

just to be sure
Item tooltip for fermenting times

and does it work!
Adds portions tooltip to uncontained food.

Not sure why this wasn't here before
"Portions" tooltip for recipes with result_mult
Fully finished brewing, adds kegs as furniture

Hopefully this should be the final version of the brewing system, bar
bugfixes if needed.
Kegs act as liquid storage, with a faucet included.
Better item handling, prevents bugs

Adds NOITEM to kegs and vats, and clears non-brew items while setting
things to brew. Should prevent most bugs, you now pretty much can only
break the brewing cycle if you deliberately try.
Buildable kegs and vats

Might be issues if they're built on top of already existing stuff.
Yeast culturing!

Harvesting yeast from vats still scrapped.
Removes tacky notice.

This is better in the PR than littering the code.
Simpler handle_liquid loop for crafting results

just, like, handle_liquid
Don't mess with legacy stuff!

Rest of changes were just github detecting... nothing
Paint walls, carpet floors, flowers
fixed picking the wrong flowers
