Sort by most recent videos instead of relevance

With the new brightcove API v6 that is compatible with v7.x-6.x, the ph library PHP-API-Wrapper controls the sort option by relevance by default. It would be better to have the media browser sorted by most recent instead of relevance especially with sites that have a lot of videos.

this can be accomplished by replacing this line:
$result = $cms->listVideos($search, NULL, $items_per_page, $items_per_page * $page);

by this:
$result = $cms->listVideos($search, '-updated_at', $items_per_page, $items_per_page * $page);
