Bug 30491: Convert saved reports tabs to Bootstrap

This patch updates the saved reports page so that it uses Bootstrap tabs
instead of jQueryUI.

To test, apply the patch and go to Reports -> Use saved.

 - On the Saved Reports page you should see multiple tabs.
 - Each should look correct and work correctly.
 - Clicking each tab should result in the table of reports filtering
   correctly for that tab (Patrons tab showing only patrons reports).
 - If necessary, edit one or more reports so that they have a subgroup.
 - Confirm that each subgroup selector is correct for each tab, i.e. a
   subgroup created under "Catalog" should only be available under the
   Catalog tab.
