Random users listings

1) Add `random_users` CSS ID for Listing Grid widget https://tppr.me/7S5Xg

2) Add follow code to the functions.php file of child theme:

add_action( 'jet-engine/listing/grid/users-query-args', function( $args, $render ) {

	if ( 'random_users' !== $render->get( '_element_id' ) ) {
		return $args;
	}

	$args['orderby'] = 'rand';

	return $args;
}, 10, 2 );

add_action( 'pre_user_query', function( $query ) {

	if ( 'rand' === $query->query_vars["orderby"] ) {
		$query->query_orderby = 'ORDER by RAND()';
	}

} );

@kaskad88 Is it possible to work with Ajax, or the infinite scroll in jetengine?
