Bug 30917: Improve course reserves breadcrumbs

This patch adds course name to the breadcrumbs and page title on the
pages for adding items to a course.

To test, apply the patch and go to course reserves.

- Click a course to view it.
- Click the "Add reserves" button.
- In the breadcrumbs you should see:

  Home > Course reserves > [Course name] > Add reserves

- [Course name] should link correctly to the course detail view. In the
  page title you should see:

  Add reserves > [Course name] > Course reserves > Home

- Enter a barcode or biblionumber and proceed to the next step. Confirm
  that the same changes are in effect on the second page.
- Perform the same tests in the "Batch add reserves" process.
