Title: Fixed bug #019508: recaptcha remote url have changed

It seems that the urls https://admin.recaptcha.net/recaptcha/createsite and http://recaptcha.net/apidocs/captcha/client.html have both been deactivated by google.
Admin is now available in https://www.google.com/recaptcha/admin/
API is now at http://www.google.com/recaptcha/api

eZComments settings should be updated to reflect this change.
