Bug 8630: Adlibris covers (intranet templates)

Changes to staff interface (intranet) templates.
Depends on new CSS clases defined in separate patch.

Test plan:

To test this particular patch (intranet templates) you need:
* The syspref patch applied
* The intranet CSS patch applied

To test:
* Apply this patch

* Enable covers (if not done already)
  * Go to staff interface, log in as a priviliged user.
  * Select "More" -> "Administration" ->
    "Global system preferences" -> "Enhanced content".
  * Set ""AdlibrisCoversEnabled" to "Show" under "Adlibris".
  * Save changes

* Add a book with a known cover/ISBN (if none exists)
  * Set MARC field 020 a,
    "INTERNATIONAL STANDARD BOOK NUMBER" to: 9780451524935
  * Set MARC field 245 a, "Title" to: 1984
  * Save changes

* Test results.tt
  * From the main intranet page, select "Search the catalog" and
    enter the title we added, "1984" and press "Search".
  * You should end up with the url:
    http://127.0.1.1:8080/cgi-bin/koha/catalogue/search.pl?q=1984
  * The cover image should be shown in the leftmost column.
  * If cover is clicked, the full cover image should be shown.

* Test detail.tt
  (continue from the search results used in prev. test)
  * Click on the title text, you should be sent to:
    http://127.0.1.1:8080/cgi-bin/koha/catalogue/detail.pl?biblionumber=2
  * The cover image should be shown on the right.
  * If clicked, the full cover should be shown.
