ssl is now required

Etsy’s API now demands ssl. I was able to fix the code by adding the necessary s in http://openapi… on line 157 of etsy-widget.php, so that it looks like:
$url = 'https://openapi.etsy.com/v2/public/shops/' . $uid . '/listings/active?detail_level=low&includes=Images&limit=100&api_key=' . ETSY_API_KEY;
