Fix highlighting logged-in user's quotes.

Forgot which element we applied the "mention" class to.
Fix removing empty editedby paragraphs.

They're not empty, they just have whitespace.
Don't add blank lines if adding a quote to an empty reply.

Bonus: nearby formatting.
Don't bother trying to load a thread tag if we can't parse the URL in a private message folder.
Don't crash loading a theme for a thread whose forum is unknown.
Fix crash tapping on homepage in a user's profile.

The homepage comes as a URL already, not as a string.
Fix posting threads that have secondary tags.

We weren't scraping the name of the secondary tag input. When attempting to
post, we'd try to set a value for the nil key and crash.
Replace SVProgressHUD with MRProgressOverlayView.

Looks nicer, and has a nicer API too.
Use Awful blue for the progress HUD thinger.
Preserve and restore sidebar visibility on iPad.
Formatting.
Fix Travis.

Old xctool version was fouling something up.
Don't linkify vote images from Mafia games.

Effectively, consider them smileys.
Load Waffleimages images from alternate host.

Waffleimages is an old image host for the Forums. For whatever reason, the
original domain does not work, but someone set up a new one. It's not a 100%
perfect clone but it's worth doing for perusing old threads.
Don't crash splitting URL queries with a bare &

There doesn't seem to be any actual spec relating to the use of a URL query, so
just ignore it. (Other options involving a key of an empty string don't seem
valuable.)
Don't ask to open a URL just copied from a post.

This is done every other time we copy a URL. This one just got missed.
