The message_received signal is emitted each time a second instance of
App with the same name as app is launched and sends a message using
send_message.
The currently running instance should check command for the action to execute and message_data for eventual
other parameters (see MessageData).
The signal handler should return a Response value depending on whether the command was successfully completed or not. If the unique_response_passthrough return value is used, the signal emission chain will continue until another handler will return another response code.
