Bug 7813: Ability to delete local cover images

This patch adds the ability to delete local cover images from the
detail page. It adds an 'X' button to trigger the deletion. It occurs
using a new SVC script called cover_images that accepts the following
parameters:

 - action
 - biblionumber (used for checking imagenumber validity)
 - imagenumber (repeatable)

It then deletes all valid images passed and returns a JSON object
containing the imagenumbers and the deletion status (1/0). The operation
is triggered using jQuery.ajax, and with the response the corresponding
images get deleted.

Note: currently one image is deleted at a time, but the code is there to
be used.

To test:
- Open the detail page fr a biblionumber containing one or more cover
  images, go to its images tab.
- Apply the patch, reload the page, go to the images tab.
- Thumbnails should look better than before ;-)
- An 'X' button should show below each cover.
- Clicking the 'X' button should trigger an alert message asking for
  confirmation.
 a) Cancel: nothing happens, reload the page and check nothing got
    deleted.
 b) Accept: the deleted image should be gone, reload the page to check
    it doesn't exist anymore and is not a browser/DOM manipulation trick.
- Signoff

Note: check having more cover images than those that fit the width and
see it wraps fine.

P.S. I chose not to implement every possible action on the svc script, but
another bug could be filled for more improvements.

Bug 7813: (follow-up) improvements for deleting local cover images

This patch:
- displays a js alert if a problem occurred on deleting the
  image on the server.
- adds a class for the new span (in order to avoid future problem, if
  someone adds a new span).
- adds a title for the [X] link.
- deal with the upload_local_cover_images permission (don't display the
  delete link if the logged in user does not have it).
- changes the license version.

Bug 7813: (follow-up) use descriptive text for delete link

This patch replaces the "times" symbol for the local cover image
deletion link with more descriptive text.  This was done because
the original "X" was small, is not necessarily going to be universally
understood to signify the deletion action, and because "&times;"
does not give much context to translators.

Bug 10868 - Use new DataTables include in catalog templates

Bug 10649 introduced a new include file for adding DataTables-related
JavaScript assets. This patch adds use of this include file to all
catalog-related pages which use DataTables.

The checkout history script has been altered to send unformatted dates
to the template, and the template now uses the "title-string" sorting
filter to enable sorting on unformatted dates.

To test, view the following pages and confirm that table sorting is
still working correctly:

Catalog -> Biblio detail page
Catalog -> Biblio detail page -> Checkout history

Comment: Sorting works. No koha-qa errors.

Note: On the issue history page:
1/ If the checkin on is empty (the item is currently checked out), the line
is sorted in last.
2/ The Renewed column is not sorted by date.
Before this patch, the sort was worse.

The aqbudgets.tt needs to use the include file too.
