Subject: [PATCH] Bug 10858: Browse selected biblios

After launching a search, some people would like to browse some results
from several pages.

This patch adds, at the OPAC, a link "Browse selected biblios >>" when
at least one biblio is checked. You can choose biblios from several
page, not the current one. In this way, checkboxes already checked
become again checked when you come back on this results page.
After clicking the link, the "Browse results" block is filled with
selected biblios, not (like as the current behavior) with the classic
results.

Test plan:
- Launch a search at the OPAC
- Check some biblios
- Go on another page
- Check some biblios
- Come back to the first page and check that already checked biblio is
  automatically checked.
- Click on the "Browse selected biblios >>" link
- Check that you are able to browse results you had checked.
