Bug 21305: Update two-column templates with Bootstrap grid: Patron clubs

This patch modifies patron clubs templates to use the Bootstrap grid
instead of YUI.

This patch also removes obsolete "text/javascript" attributes from
<script> tags in the modified templates.

To test, apply the patch and view the following pages, confirming that
they look correct at various browser widths:

 - Tools -> Patron clubs
   - View club enrollments
