Added inertia simulation for compass heading: In previous version calculated compass values were directly used for visualization of the compass. This causes a fast changing (jumping) of values. With the inertia introduction the compass behalfs more like an analog compass. The final value is reached slowly and the displayed values are more stable. For configuration a new menu item has been added to the compass menu allowing to switch inertia off (default), small and large inertia simulation
