Bug 26120: Remove the use of jquery.checkboxes plugin from tags review template

This patch removes the use of the jquery.checkboxes plugin and improves
the handling of tag status markup so that the "Select all pending"
selection link works correctly.

To test, apply the patch and go to Tools -> Tags. To test properly you
should have multiple tags awaiting moderation.

 - The initial view of tags moderation shows only tags awaiting
    moderation. Test that the "select all," "clear all," and "Select all
    pending" links work correctly.
 - Click the "Approve" button for a tag, and the "Reject" button for
   another tag.
 - Test the "Select all pending" link again. Only the tags awaiting
   moderation should be selected.
