Subject: [PATCH] Bug 6950: Hide the resort option when searching for a tag

If you click a link from the Tag Cloud, the results page offers the
usual select menu to resort your results. However, doing so resubmits
the search as a standard keyword search.

Test plan:
1/ Click on a tag
2/ Confirm that the resort dropdown list does not appear.
