Minor cleanups for current user popup panel

Wrap the two links (Settings, Sign-Out) into a single div and supply a
min-width of 175px.  This prevents them from collapsing in an odd two
line display when there is no avatar present.

Remove the div altogether when viewing another user's popup panel,
rather than just hiding the links.  This makes the DOM slightly
smaller for the common case of viewing someone else's information.
