• Fixed behaviour of Message.get_message_encoded_size() to return accurate size.

• Added new optional callback argument to client.mgmt_request to allow for custom handling of different status codes.

• Added new client methods auth_complete() and client_ready() to allow for more fine-tuned monitoring or the client opening stages.
