Major change to the Console provided by this library. The interface de.ugoe.cs.console.ConsoleObserver? is deprecated and split into the five interface IOutputListener, IErrorListener, ITraceListener, IExceptionListener, and ICommandListener.
The rational for this change is to provide the possibility to listen to only parts of what is send to the console to provide better capabilities for target-oriented handling of the different streams, e.g., for exception logging.
