 Bug 15952: Moving cataloging search actions into a drop-down menu

Edit: Have removed the datatables stuff - wasn't necessary. Also fixed a
merge conflict
Edit: Comment 7

To test:
1) Go to Cataloging and do a search in the catalog and reservoir
   (cataloguing/addbooks.pl)
2) Confirm that for the results found in catalog, the options (MARC and
   Card preview, Edit biblio, Add/edit items) are there and behave as
   expected.
3) Confirm that for the results found in reservoir, the options (MARC
   and Card preview, Add biblio) are there and behave as expected.
4) Set user permissions so that the user cannot edit the catalog or
   items. (editcatalogue -> edit_catalogue and edit_items)
5) Confirm that you no longer see the options to edit or add
   items/biblio in either table.
