[PATCH] search_view: various navigation tweaks

[Eric Wong <e@80x24.org>]

This improves the "&x=t" navigation between the thread overview
(skeleton) section at the bottom and jumping back to the top for
the mbox download form.  The "--links below ..." text ought to
be helpful for users unfamiliar with the /$MSGID/T/ and /$MSGID/t/
views.
