/// Since v1.25 this method has one parameter: object[] playerAndUpdatedProps, which contains two entries.
/// [0] is the affected PhotonPlayer.
/// [1] is the Hashtable of properties that changed.
///
/// We are using a object[] due to limitations of Unity's GameObject.SendMessage (which has only one optional parameter).
///
/// Changing properties must be done by PhotonPlayer.SetCustomProperties, which causes this callback locally, too.
///
/// Example:
/// void OnPhotonPlayerPropertiesChanged(object[] playerAndUpdatedProps) {
/// PhotonPlayer player = playerAndUpdatedProps[0] as PhotonPlayer;
/// Hashtable props = playerAndUpdatedProps[1] as Hashtable;
/// //...
/// }
///
