Bug 10730: Use DataTables on the tag review page

This patch enhances the tags review page in the staff client by adding
DataTables sorting to the table of tags.

It also converts the tag list page (list.tt) to use the new DataTables
include introduced by Bug 10649.

To test, apply the patch and view the tags review page for various
categories: Pending, approved, rejected, all. The table should be
sortable by status, term, weight, and date. Sorting by date should work
correctly regardless of date format preference. Title sorting on the tag
list page should work correctly.
