Themable set of navigation plasmoids.

Dataengine require configured and started gpsd daemon.

Right now 2 widgets are implemented.

Compas - just show headding.
speedometer - show current speed. Pressing number you can set speed limit. When limit is over - the KDE notification is emitted. When speed is over, every 10-nth seconds dong dong emitted (notification also). When speed is down notification is also emitted.

When there are no gpsd, lost fix - arrows became black.

Next plasmoid - track recorder and shows sensors - like odometer and average params.
