How to get tag search result list to order by last post date?

[grey_goose]

Pretty crazy this is so buried. Had to dig it up since we've been using tags more and more. The default behavior of sorting by when the tag was added rather than by thread/post dates is... a really strange decision.

Change line 95 to "ORDER BY threadid ASC" to get threads from oldest to newest.
Change line 95 to "ORDER BY threadid DESC" to get threads from newest to oldest.

Ordering results by last post date would require JOINing the thread table but that looks like it would require some extra evaluation of 'contenttype' -- I'm guessing for people with CMS/Blog, which I don't have.

Still, ordering by threadid (thread started) will put them in some semblance of order for most rather than the pure WTF-ery of sorting by tag-added date.
