Bug 30457: Convert holds page tabs to Bootstrap

This patch updates the holds page to replace jQueryUI tabs with
Bootstrap.

To test, apply the patch and begin the process of placing a hold on a
title in the catalog.

If you have one or more patron clubs configured:
 - You should see two tabs, Patrons and Clubs.
 - Both should look correct and work correctly.
 - The Patrons tab should be selected initially, with cursor focus in
   the form field.
 - Switch to the Clubs tab. The cursor focus should move to the form
   field under this tab.
 - Submit a club search which will return results.
 - The page should refresh and the clubs tab should be preselected,
   showing the search results.

If you have no patron clubs configured, the page should show only the
Patrons tab.
