Take into account the satellite motion when resetting its velocity.

Browse Source 
- in the binaries problem we have to reinitiate the velocity within
   the satellite properly, taking into account not only the speed of
   wind at the surface, but also setting the satellite's velocity due to
   its orbital motion; this produces properly the bow shock in front of
   the satellite, and the new time step is calculated correctly since it
   includes the speed of the satellite;
