Bug 14741: Selecting all child permissions doesn't select the top level check box

This patch modifies the patron flags page so that manually selecting all
the child permissions also checks the checkbox for the parent
permission.

To test, apply the patch, open a patron record, select More -> Set
permissions.

 - Expand a set of permissions, for instance "Add, modify, and view
   patron information."
 - If any boxes are checked, uncheck them.
 - Check each of the "child" checkboxes ("Add, modify, and view..." and
   "View patron infos..." ).
 - When both checkboxes are checked, the "Add, modify, and view" parent
   permission should be automatically checked.
