Bug 34773: Improve translation of title tags: Cataloging tools

This patch modifies cataloging tools templates so that title tags can be
more easily translated. The patch also makes some modifications to
titles, breadcrumb navigation, and page headers in order to make them
more consistent with each other and with other similar pages.

Note that stockrotation.pl has been modified so that rota information is
available to the template in more cases for the purpose of showing that
information in navigation and headings.

To test, apply the patch and go to Cataloging. Test each page and each
variation of the page to confirm that titles, breadcrumbs, and page
headers look correct.
