From: dirk husemann <hud@zurich.ibm.com>

attached is a patch set that
     * adds further robustness checks for the CreateUser and CreateRegion
       XmlRpc
     * fixes SceneManager.TryGetScene(IPEndPoint, Scene) --- contrary to my
       expectation IPEndPoint.Address is not sufficient for a comparision,
       IPEndPoint.Address.Address (the long representation) does work
       however.
     * add [RemoteAdmin] section to OpenSim.ini.example
     * fixes XML doc comments
       good night,
       dirk
