(Suggestion) YouTube Thumbnail with better quality

Really like your plugin so far, it get’s the job done. Except for one thing I’d change:
The YouTube thumbnails (unlike vimeo thumbnails) are really low quality because the plugin is fetching the default.jpg of a video url and not a higher quality option like hqdefault.jpg.

So I’ve modified line 156 in facebook-and-digg-thumbnail-generator.php:

if ($yt_id) {
	$image = "http://i4.ytimg.com/vi/$yt_id/hqdefault.jpg";
	$meta_imgs[] = $image;
}

Other available options would be: mqdefault, sddefault or maxresdefault.

It would be a great addition to the plugin if this would find its way into the options! But I wanted to share this anyways.
