Bug 34855: Use template wrapper for breadcrumbs: OPAC part 3

Bug 34855: Use template wrapper for breadcrumbs: OPAC part 3

This patch updates several OPAC templates so that they
use a new WRAPPER for displaying breadcrumbs.

This patch also updates html_helpers.inc to add some logic for handling
the case where the "Home" link is the only breadcrumb (on the OPAC main
page). The change allows for the link to be disabled in this case.

Apply the patch and log in to the OPAC. Test each of the following pages
and their variations. Breadcrumbs should look correct, and each link
should be correct:

- OPAC main page
- Course reserves
  - Course reserves details
- Libraries
  - Follow the link for a specific library
- View the details of a bibliographic record
- Navigate directly to
  /cgi-bin/koha/opac-downloadshelf.pl?shelfnumber=X where X is the id of
  an existing list. (I don't think this page is ever seen unless the
  user has JavaScript disabled).
- Locate a serial record and click the "More details" link under the
  "Subscriptions" tab.
  - Click the "Full history" tab.
- Log into the OPAC as a user with checkouts. Navigate directly to
  /cgi-bin/koha/opac-issue-note.pl?issue_id=X where X is the id
  (issue_id) of one of the user's checkouts. (Another page which is only
  accessed directly if the user has JS disabled).
- From the logged-in user summary page, click "Change password"
  - Submit a password change.
- With "UseRecalls" enabled, locate a bibliographic record you can place
  a recall request for.
  - Place a recall.
- With "OPACLocalCoverImages" enabled, locate a bibliographic record
  which has a local cover image attached.
  - Under the "Images" tab, click the image thumbnail.
- If you have no custom OPAC pages, go to Tools -> Pages in the staff
  interface anc create one.
  - View the page in the OPAC.
- With "OPACReportProblem" enabled, click the "Report a problem" link at
  the bottom of any OPAC page.
  - Submit a report.
