Matthew Flaschen f9c5808912 Move edit-user-talk to messages
Also:

* Clear the newtalk flag when they mark all their edit-user-talk
  read.

* Remove the section caching system.  It was designed to avoid
  performance problems with Flow messages, but now that standard talk pages
  are in 'messages', messages should be relatively common (alerts
  were already not cached by this).

* Minor cleanups to reflect that messages are not only Flow (and
  a typo fix in the Gruntfile).
