GpsListModel was one of those "special" singletons that could be created explicitly with new. This would make sense if a parameter were passed to the constructor. We only passed null, so one might as well turn that into a classical singleton with default constructor. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
