Bug 34980: Remove the use of event attributes from title-actions-menu.inc in OPAC

This patch updates the include file used to show actions with each
search result, removing two instances of "onclick" in favor of an event
handler class which was already in use elsewhere.

To test, apply the patch and log in to the OPAC.

- Perform a catalog search which will return results.
- Test the "Save to lists" link under any search result. The "Save to
  lists" pop-up window should appear.
- View the contents of a list which contains some titles.
- Test the "Save to another list" control. The same pop-up window should
  be triggered.
- Tag at least one title in the catalog and view the "Tag cloud" page.
- Perform the same test with the "Save to lists" button in the table of
  our tags.
