add event logging for move_listener events
adding startup notification capability so that clients can optionally display an important message to users upon app startup.  the message is sent via the get_config response and is intended to be displayed in a popup on the client.  if STARTUP_NOTIFICATION_MESSAGE has no value, client will not display the popup.  eventually, this will be replaced with a more flexible and robust notification system.
