[staging only] Show Recent Group PMs in right sidebar.

Show up to 10 of your recent group PM conversations in the right
sidebar.  Clicking on the links narrows to the huddle and opens the
compose box for the huddle.  The green circles have opacity
proportional to the number of users present in the huddle.

This is feature flagged to staging only.

Some of this code was written by Allen before commits were squashed.

Known issue: unread counts disappear on certain refresh events.
