Updated default (developer) values so that they are valid (especially the server address).
Renamed a few methods and variables. Added also default config entry CONNECT_TO_SERVER (default: true).
Added a first draft of the connection toggle button, but it's not completely functional so far.
Removed the unnecessary MQTT entries (host and port) since this information is already in the Beam address (server part of user address).
Corrected a bug where the server was not correctly set up after the wizard.
Integrated logger as dependency (for injection).
Added HandshakeResponseHandler in order to use the same concept of handling messages as on the server side. This simplifies the ConnectionModel.
Cleanup.
Integrated Logger injection.
Adapted to new concept of MessageHandlers.
Integrated Logger injection and started working on connections to MQTT broker.
Updated assembly dependency.
