`redirect_to` bug with multiple parameters

redirect_to should work with multiple parameters like url_for() does.

easy to fix

function redirect_to($params)
{
  # [NOTE]: (from php.net) HTTP/1.1 requires an absolute URI as argument to » Location:
  # including the scheme, hostname and absolute path, but some clients accept
  # relative URIs. You can usually use $_SERVER['HTTP_HOST'],
  # $_SERVER['PHP_SELF'] and dirname() to make an absolute URI from a relative
  # one yourself.
  
  # TODO make absolute uri
  if(!headers_sent())
    {
    $params = func_get_args(); // adding this allow multiple parameters like in url_for
    $uri = call_user_func_array('url_for', $params);
    stop_and_exit(false);
    header('Location: '.$uri);
    exit;
  }
}
