Add custom WP_Query loop attributes

Hi there,

could you add custom WP_Query attributes to the widget? I coded it locally, it looks like this:

//custom wp-query arguments
    if( ! empty ($args['wp_query'])){
        $string = $args['wp_query'];
        $a = explode(';', $string);
        foreach ($a as $result) {
            $b = explode(',', $result);
            $array[$b[0]] = $b[1];
        }
        $query = array_merge($query, $array);
    }

It allows filtering for custom fields, or other miscellaneous things, separated by commas and semicolons. I used it to filter woocommerce products by featured (“meta_key,_featured;meta_value,yes”).

Thanks for a great plugin!
