Spit and polish

* Add a distinctly colored title and background for DM threads apart
  from the public channels
* On the Who List, the profile picture is clickable to open profile
  links
* Fix auto-scrolling issues: it won't autoscroll if the new message was
  in a different channel, and when toggling between channels always
  scroll back to the bottom of that channel
