Bug 31678: Convert authority editor tabs to Bootstrap

This patch modifies the authorities editor template to replace jQueryUI
tabs with Bootstrap tabs. The changes should have no visible effect,
with all previous functionality still intact.

To test, apply the patch and go to Authorities -> New authority.

- When the page first displays, the "0" tab should be active.
- Test that each of the numbered tabs works correctly to activate the
  correct tab content.
- Confirm that the numbered tag anchors still work correctly.
- Append a specific tab anchor to the URL, e.g. "#tab4XX" and refresh
  the page (you may need to shift-refresh). When the page reloads the
  correct tab should be active by default.
- Confirm that sortable subfields can still be re-ordered by dragging
  and dropping them via the "stacked lines" icons.
