Bug 27571: "Add to lists" on MARC and ISBD view of OPAC detail page doesn't open in new window

This page corrects the global click handler in the OPAC so that all
"addtoshelf" links will work correctly to trigger the popup window for
adding titles to a list.

To test, apply the patch and test the process of adding a title to a
list in the OPAC from various places:

- Search results
- Bibliographic detail page (normal)
- Bibliographic detail page (MARC view)
- Bibliographic detail page (ISBD view)

Test both adding to an existing list and adding to a new list.
Everything should work correctly.
