Bug 10856: (Follow-up) improve behavior of the "close shelf browser" …

…link

In Firefox at least, the shelf browser cannot be reopened after
hiding it with the "close shelf browser" link. This followup improves
the behavior of the "close shelf browser" link so that the shelf browser
can be redisplayed.

To test, open a bibliographic detail page in the OPAC and click a
"browse shelf" link. Click the "close shelf browser" link--the shelf
browser should be hidden. Click the original "browse shelf" link and the
shelf browser should reappear without reloading the page.

Test with Firefox and Chrome (at least).

All tests and QA script pass.

Testing notes:
- New unit tests in t/db_dependent/ShelfBrowser.t pass.
- System preference  OPACShelfBrowser still works as expected.
- Closing and opening the shelf browser works as expected.
- Next and Previous links show new and nicer behaviour.
- Logs are clean.

Tested with Firefox and Chromium under Ubuntu.

Notes: The currently displayed record could maybe be highlighted
a bit better.
