PHP error: Function create_function() is deprecated

Your plugin is generating a PHP error, and it is:

PHP Deprecated: Function create_function() is deprecated in [...]/wp-content/plugins/like-box/includes/widget.php on line 179

I have fixed this by replacing line 179 from this:

add_action('widgets_init', create_function('', 'return register_widget("like_box_facbook");'));

to this:

add_action('widgets_init', 'like_box_register_widget');

function like_box_register_widget() {
	return register_widget("like_box_facbook");
}

Please do the same so that I don’t have to fix the plugin after every update.

Thanks.
