Add Sorting of Testimonials when in list mode to support Testimonial Data Field

[amallory]

In the admin screen when editing a testimonial you can specify the order of the testimonials in a "Testimonial Data" field. It would be good to carry this through to the front end and allow ordering the list of testimonials on this field when using the shortcode.

This code can be used in the interim to accomplish this:
add_filter ('testimonials_in_page_args', 'testimonials_sort_testimonial_order_meta');
function testimonials_sort_testimonial_order_meta($filtercont) {
$filtercont['meta_key'] = 'ivycat_testimonial_order';
$filtercont['orderby'] = 'meta_value_num';
$filtercont['order'] = 'ASC';

return $filtercont;

}
