New-ish Feature: Sub-Domains

Authorized users can now create sub-domains, which are basically what "zones" used to be, but they have a different url, slightly improved functionality, and are hopefully slightly more convenient. Sub-domains will be limited to the home page only. Example:

https://troma.trashepics.com instead of https://trashepics.com/zone/troma/

For the Troma domain, all posts tagged with "troma" will be displayed, as well as all posts grouped under a movie tagged "troma". This will make it easier to have them appear in the zone/domain. Sub-domains now include a search feature, relevant news, and forum/post display toggles.

I had to re-arrange a lot of shit to make these work, so if I fucked up your zone, yell at me.
