[Merge] lp:~stylistica/postorius/user_preferences into lp:postorius

[Terri]

Review: Approve

We're looking for some "easy" bugs to fix at the GHC Open Source Day, so I'm actually going to merge this as-is and then let our new contributors find the style problems as simple first commits.  (I know, I know, this isn't how it's supposed to be done, but it'll be fun!)
