You're welcome. I'm in fact sorry that I had to temporarily revert this
commit in order not to crash at startup...

OK, had overlooked this one a while ago when I was doing the
FileManager/PlacemarkManager split.

I think the fix I commited improves the situation.
Now the rendering still happens with the old gpx file handling, and a
GeoDataDocument is created as well.

When there is good enough rendering for GeoDataDocuments polygons, then 
MarbleModel::openGpxFile() will spare doing the gpxFileModel->addFile.
