Instead of maintaining a seperate latitude/longitude values in C++ and passing them to QML separatelly, pass them as a QGeoCoordinate. This reduces the number of model "roles" and also prevents the creations of extra objects in QML (e.g. via QtPositioning.coordinate(..)). Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
