Bug 22102: Markup fixes for OPAC article request page

This patch makes a few improvements to the OPAC article request page:

- Improve the breadcrumbs menu by adding a link to the title
- Add a header with the record's title
- Wrap the "no article requests" message in the correct dialog div
- Remove obsolete CDATA marker

To test, apply the patch and log in to the OPAC

 - Peform a search which will return multiple results
 - Click "Request article" on a title for which article requests can be
   submitted.
   - Confirm that the breadcrumbs menu looks and works correctly.
 - Click "Request article" on a title for which article requsts are not
   allowed.
   - Confirm that the message is correctly styled.
