Bug 9465 - Use DataTables on update child to adult patron page

Replace the tablesorter plugin with the DataTables plugin on the
update child to adult patron page.

Added default sort by patron category description (ascending).

To test, open a patron with a child category type. Choose the 'Update
child to adult patron' item from the 'More' menu. Confirm that
table sorting works correctly in the popup.
