Bug 9675 - Replace YUI buttons on authorities home page with Bootstrap

This patch converts the toolbar include file used by the
authorities home page and authority view page
(authorities-home.pl and authorities/detail.pl) replacing YUI button
and menu code with Bootstrap.

To test:

- View the authorities home page and confirm that the "New
  authority" button looks correct and works correctly.
- Search for an existing authority and click the "Details" link to view.
  "Edit," "Delete," "Save," and "New authority" buttons should look
  correct and work correctly. The "Delete" button should only appear for
  authorities which are unused.
