This ports Aurora Cooking, sometimes called Nanako Cooking, from CitRP, who got it from Aurora originally.

Pulled from here with updates to to_chat()

Ovens and fryers now work like the microwave, but also have special trays/baskets that can be inserted and removed with things on them. There's also a crapton of new recipes. Note that you can still use the oven to just bake things, or produce variable food items, to my knowledge. This was specifically kept in when it was originally implemented, IIRC.

- Cooking now uses several machines to make recipes. Microwave, oven, deep fryer.
- Recipes have been redone to reflect this.
- Adds a reagent called Space Spice (used in Synnono's food recipes mostly, prevents recipe conflicts)
- New foods! Lots of them.
- You can cook using held mobs. Also, mouse/ratburgers.
I can dump the recipes if you'd like.

This is WIP, and will not compile just yet.

Now onto the bugfixing nightmares!

Microwave not cooking micros/mice: Fixed
Invalid Recipe datum thanks to /microwave prefix: Fixed
Fryer earsplittingly loud: Fixed
Fryer/Oven continuing to cook even after items removed: Fixed
Oven having 'on' icon state when door closed but off: Fixed
Appliances not scaling cooking time/damage based on size: Fixed
Feature added - Burning Food will set off fire alarms and set off a black cloud of smoke!
Overcook time reduced to allow for less margin of error (IE Actively requires you to pay attention)
Multiple Microwave bugfixes, including multicooking/etc not working, recipe errors, icon state errors, ejection errors.

Cooking times are now no longer 10-15 minutes per item, the LARGEST items will take around ~4-5 minutes, 6 at the maximum in the case of the superbigbite (one of the most filling food items in the game).
Cooking oil tanks added
Appliances are now constructible instead of being eldritch black magic
Recipes are now reorganized to either fryer/oven/grill based on where they're made (Although recipes_microwave still needs a LOT more sorting)
Critical time bug with cooking fixed, AND you can now upgrade your appliances for even higher efficiencies!
