open_source / mqtt-cpp

added LWT ( last will & testament ) option to mqtt connect.

added support for a last will & testament message. LWT settings are not required for connection, but can be provided as optional parameter when calling the mqttclient connect function. ( see publisher test case ). The parameters to be added are the topic to publish on and the message to be published in case of a connection disruption.
