One more NMEA problem solved

Abie pointed me to a very stupid bug in the NMEA processing of RouteConverter. Starting with version 1.8, I've replaced the older GPSBabel based implementation by a self written one. The intention was to

• make the processing faster
  
• interpret a wider set of NMEA sentences
• merge NMEA sentences which describe the same position

Obviously, this comes with a price: It takes some time to stabilize the code. Please try the new version 1.9.2 which solves the problem that NMEA positions in the south east are misinterpreted as south west.
