visualizer+mobility: A specialized version of GetObject (GetMobilityModel) is now implemented in MobilityModel class. This method is now used by the visualizer to obtain mobility interface.

This trick is necessary in order to use in python mobility models that
are not explicitly exported (or impossible to export) to python bindings
generation.
