Callback for the janrain_capture/simple_logout menu item.

Logs out the user without redirecting to a regular Drupal page. This endpoint can be used by services that need to log the user out without incurring the overhead of a redirect and processing of a full-blown Drupal page. It is particularly useful for Janrain SSO's Javascript, which calls the logout link using a dynamically created iframe and may break if iframe busters are used by the Drupal site.
