* initial structural modifications to start with MHD development (Noble/Ott)

  -> add comoving b-field: bcom[3] and bcom0 
  -> add integer variable MHD which is set in ParamCheck to 0 or 1 
     according to HydroBase::Bvec_evolution_method being GRHydro or something
     else (don't want to do string comparisons very often)
  -> skeleton routine Conservative2PrimitiveM in separate .F90 file
  -> extend keyword Bvec_evolution_method with "GRHydro"

* code compiles, should not hurt anything already there, does not do 
  anyting (yet)
