Bug 9672 - Replace YUI buttons on MARC editor page with Bootstrap

This patch converts the buttons on the MARC editor page to Bootstrap,
replacing YUI button and menu code with Bootstrap markup.

Various workflows must be tested to confirm that functionality
remains unchanged:

- Edit existing record. Clicking the "save" button should redirect
  you to the default "view" page for that record.
- Create a new record. Clicking the "save" button should redirect you to
  the add/edit items screen.
- When creating or editing a record, test the dropdown menu attached to
  the "save" button. Each function should work correctly.
- Test using a user who does not have "edit items" permission. There
  should be no menu attached to the "save" button.
- Test using fast cataloging through circulation. A single save button
  should appear, redirecting to items.

In all cases validation should proceed before saving. Leave a required
field empty to test.

Testers should also confirm that Z39.50 button works as expected and
changing frameworks still works as usual.
