A pinned item goes to the top of its list

order_sql takes pinned_first, which puts coalesce(s.flagged, 0) DESC ahead of
the chosen sort, so pins lead every list in whatever order is asked for and on
every page of it. Not when sorting by the pin column itself, where the direction
is the point, and not for Currently Listening. Pinning now asks for the list again
so the row moves at once, instead of redrawing it where it stood.

Closes #35.
