Extended event based communication model.
* octave-event-listener.h: New interface for event listeners.
* octave-qt-event-listener: Implementation ov event listener for Qt.
* main-window: Added event listener and connected signals.
* octave-event-observer.h: Renamed ignore-method and added comments.
* octave-event.h: Removed type information and added process method instead.
* octave-link: Removed QObject subclassing.
* src.pro: Added new files to project.
* workspace-model: Removed QTimer, since it not in a Qt event loop anymore.
* workspace-view: Added QTimer from the model temporarily.
