 * Using jQuery UI to add "drag and drop" reordering of items in the admin list view. The model must have an "order"
 * field to store the order value in.

 * Add the following to your model admin
 * class Media: js = ['/media/js/path-to-jquery.js', '/media/js/path-to-jqueryui.js', '/media/js/sortable_list.js']
