Fix layout bug
Work around Twitch's broken `urlize`.
Fix chat log emotes

* Fix bug where sub-only emotes would leak into the global emote space as soon as any user with access to them posted
* Copy logic from Twitch chat JS to stop word emotes from triggering inside other words (eg `test:-)test` should still match, but `testlrrFRUMPtest` should not)

Make !next plug desert bus.

Also add undocumented !desertbus command to do the same thing, since people insist on trying that in chat.
