[SailfishDevel] QGeoSatelliteInfoSource in Sailfish

Hi Chris,

I've pushed my existing code to github for you, but be warned, it is chaotic, 
and my first "real" qt project. There is a lot to do...

https://github.com/balta3/sailfish-gpsinfo

The QML position source is working here, and you can see the compass access, 
too. Is there any existing QML component for SatelliteInfoSource? I try to 
access it in C++ as I could not find any in the Qt documentation.

Greetings,
Marcel
