Bug 34393: Fix inconsistencies in MARC bibliographic framework page titles, breadcrumbs, and header

This patch fixes some inconsistencies in the MARC bibliographic
framework administration page, making sure the page title, breadcrumb
navigation, and page headers are consistent with each other.

The file admin/marc_subfields_structure.pl is modified so that it
provides the framework name to the template.

Test each page to confirm that page title, heading, and breadcrumbs are
consistent:

- MARC bibliographic frameworks
  - New framework
  - Edit framework
  - Delete a framework which is not used
  - Delete a framework which is in use
  - Framework MARC structure
    - New tag
    - Edit tag
    - Delete tag
    - View subfields
    - Edit subfields
