/**
 * Randomly reorder child elements.
 * The optional *callback* is called with each child and its new (deep) clone, allowing you to
 * copy data over or anything else you may require.
 *
 * Example usage:
 * controls.songs.reorder(function(child, clone) {
 * clone.data('info', child.data('info'));
 * var id = child.data('info').id;
 * if (self.current != undefined && self.current.data('info').id == id) self.current = clone;
 * if (self.next != undefined && self.next.data('info').id == id) self.next = clone;
 * });
 *
