Support autoplay for Vimeo videos

This patch worked for me. Except that the location of the file is incorrect. It should be: emfield/contrib/emvideo/providers/vimeo.inc not contrib/video_cck/providers/vimeo.inc. Also, this bit at the end seems unnecessary:

@@ -215,4 +215,4 @@ function video_cck_vimeo_preview($embed,
 function video_cck_vimeo_thumbnail($field, $item, $formatter, $node, $width, $height) {
   $xml = emfield_request_xml('vimeo', 'http://vimeo.com/api/oembed.xml?url=http%3A//vimeo.com/'. $item['value'], array(), TRUE, FALSE, $item['value']);
   return $xml['OEMBED']['THUMBNAIL_URL'][0];
-}
\ No newline at end of file
+}

Yes, the $autoplay is being ignored by the embed code. This one worked, thanks!

cheers, Ronald
