Bug 31993: Improve specificity of authorized values breadcrumbs

This patch adds a link back to the current authorized value category to
the breadcrumbs. The page title has also been modified to match.

To test apply the patch and go to Administration -> Authorized values.

- Click an authorized value category, e.g. CCODE.
- Click "New authorized value for CCODE"
- In the breadcrumbs menu you should see: "Home ->  Administration ->
  Authorized values -> Authorized values for category CCODE -> New
  authorized value.
- The "Authorized values for category CCODE" link should take you back
  to the correct view.
- The page title should match.
- Return to the list of CCODE authorized values and open one for
  editing.
- The breadcrumbs should include a link back to "Authorized values for
  category CCODE"
