This patch adds Ajax-based tablesorting to tablesort.inc. Note that this
is /not/ client-side sorting, which isn't that useful in Drupal as most
sortable tables are paged. Of course, given that it still requires a
round-trip to the server, the biggest advantage is in visual usability,
as only the table itself changes and not the entire page.

The way this is accomplished will probably strike you as very elegant,
or very dirty ;). In order to avoid patching up every instance of a
sortable table and providing a custom Ajax menu callback for each, I
made it so that inside theme('table'), the tablesort can cause the
table to be printed immediately and PHP to quit. This is triggered by
the GET variable 'tablesort', when set to the table's id.

So, the Ajax HTTP request visits the exact same page as the original
page, it only adds something to the URL which triggers this special

It works really well. In fact, the id-per-table wouldn't be necessary
if we restricted ourselves to one sortable table per page.
