Title: OneLogin doesn't expect rawUrlEncoded spReturnUrl

The most recent commit mentioned that the standard uses specific urls, but when OneLogin receives those urls, it does not urldecode them, so the redirection step to consume.php does not work. Don't know where the fix should be made, but it doesn't work with the call to rawurlencode.
