Bug 24393: Remove event attributes from patron clubs list template

This patch removes some instances of the "onclick" attributes from the
template that lists patron clubs and templates.

To test, apply the patch and go to Tools -> Patron clubs.

 - Test the process of deleting a club template. Clicking the "Delete"
   button should trigger a confirmation. Confirming should delete the
   template.

 - Test the process of deleting a club. In the "Clubs" section of the
   page, click the "Actions" menu next to any club. Clicking the
   "Delete" link should trigger a confirmation. Confirming should delete
   the club.

 - Also in the "Clubs" section of the page, find a club which has
   enrollments. Select "Search to hold" from the "Actions" menu. It
   should take you to the advanced search. On the search results page
   you should have the option to place a hold for the club you selected.
