 When uploading a file with a forbidden extension using the multi-file
 uploader, the upload will (of course) fail. But the "crunching" bar
 remains visible, and if the Gallery tab is visible, the attachment count
 is wrongly incremented.

 Will also happen if there are directory permission issues ('cannot write
 to directory', 'uploaded file could not be moved').

 Although the correct error messages are sent from async-upload.php, the js
 (wp-includes/js/plupload/handlers.js) looks for a particular string to
 check if the response is an error, and this string is not present.

 Patch adds the string as an easy fix.
