Bug 22045: Cataloging UX enhancement - Improve access to tabs

This patch makes style changes to the standard MARC editor with the goal
of both making it more responsive and making it easier to navigate among
tabs and tags.

Tabs are now part of the page's toolbar, which floats as the page
scrolls. In addition to the numbered tabs, there is also a section
showing in-page links to the MARC tags which are available on that page.

To test, apply the patch, regenerate the staff client CSS, and clear
your browser cache if necessary.

Open a blank or existing record in the standard cataloging editor. Test
the redesigned tabs, the floating toolbar, and the in-page tag links.
Confirm that everything works well at various browser widths.
