Adds an origin and culture system to govern possible faction items, citizenships, accents, religions.

[NonQueueingMatt]

As per title, this will vanquish or at the very least help with a lot of problems (such as people missing naming/skintone requirements for certain human factions or people grabbing faction items not meant for their factions).

The intent is for accents, citizenships and religions to also be limited to what that specific origin allows you to pick as well.

To-do:

• Head staff approval.
• Get the loreteam to draft up a list of origins + cultures for every faction of every species, plus possible citizenships/accents/religions for that origin.
• Add possible species overrides for cultures and origin.
• Possibly change accents/citizenships/religions to use decls.
• Figure out how to save the Origins settings in the database, since I don't think we can save types. Since they must be strings, I guess I have to make a list on some subsystem.
• Sanitization fixes.
• Add culture/origin selection to antags (specifically, the changer machine).
• Add culture/origin to human default init, since right now it's only a pref thing while it's a proof of concept.
• SQL.
