Bug 33524: Use template wrapper for tabs: Authority editor

This patch updates the authority editor template to replace tab markup
with the use of WRAPPERs. Some CSS and JS has been modified in order to
make the custom style and behavior of the tabs on this page work
correctly with standard Bootstrap tab markup.

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

- Confirm that the tabs look correct, with the same style they had
  before the template change.
- The first tab ("0") should be selected by default.
- Confirm that tab-switching works correctly: The tab color should
  change and the list of numbered tags in the menu just below should
  change to match the section.
  - Confirm that these tag number links still work correctly to jump you
    down the page to the corresponding tag.
- Without filling in any mandatory fields, click the "Save" button.
  - You should get an error message about missing mandatory fields.
    - Clicking the "Go to field" link should take you to the correct tab
      and the correct tag.
- Append a hash to the URL to pre-select a tab other than the first one,
  e.g. "/cgi-bin/koha/authorities/authorities.pl?authtypecode=PERSO_NAME#tab5XX_panel"
  The correct tab should be selected upon page load.
