do not set conservatives, remove TOV_Atmosphere
remove TOV_Atmosphere[] from the code and no longer set the conservative
variables. Instead TOVSolver relies on GRHydro to set the conservatives in
InitialPrim2Con and to enforce atmosphere in initialatmospherereset. This also
fixes any asymmetry in atmosphere handling between the stars.
