Garry Collum 45069c1ca4 Bug 3229: Fixes sort-by feature for jquery tablesorter in lists. 
This patch adds some variables for the sortfield that are passed through the URL so that the sort-by feature works when the jquery tablesorter is used for a list of titles in opac-shelves.tmpl.

=item C<modifyshelfcontents>
If this script has to modify the shelf content.
=item C<shelfnumber>
To know on which shelf to work.
=item C<addbarcode>

Load template with 'viewshelves param' displaying the shelf's information.
=item C<shelves>
If the param shelves == 1, then add or delete a shelf.
=item C<addshelf>
If the param shelves == 1, then addshelf is the name of the shelf to add.
