create_function is depricated notice

I was getting the following error with PHP 7.2:

[04-Dec-2018 12:55:14 UTC] PHP Deprecated: Function create_function() is deprecated in /wp-content/plugins/bbpress-advanced-recent-topics-widget/bbpress-advanced-recent-topics-widget.php on line 188

My fix was to change line 188 to this:

add_action('widgets_init', function() { register_widget("BBP_Recent_Topics_Widget_Advanced"); } );
