Bug 26798: Remove the use of jquery.checkboxes plugin from patron detail page

This patch removes inclusion of the jquery.checkboxes plugin from the
patron detail page (moremember.tt). The plugin is unused.

To test, apply the patch and locate a patron with checkouts.

- View the details for that patron.
- Open the checkouts tab and click "Show checkouts" if necessary.
- In the table of checkouts, confirm that the "select all" and "none"
  links in the "Renew" and "Check in" column headers work correctly.
