Cleanup of signal/slot handling between the dolphin view and the main window: now the main window listens to the signals from the dolphin view and connects to private slots (previously the dolphin view connected to public slots of the main window). Also prevent naming all slots by the prefix 'slot', describe instead what the method does.
