db606cfa1a Use primitive variables in the Riemann solvers. 
There is no need to convert conservative variables to primitive ones,
since they are already up to date, so pass primitive variables directly
to Riemann solvers in subroutine update_flux().

5ce57da3bc Calculate directional fluxes in update_flux() only. 
- instead of calculating all fluxes at once in update_flux(), select
   the direction as a subroutine argument and calculate only the flux
   along this direction;

 - directional fluxes are needed for the directional RK integration of
   the numerical fluxes;

 - update subroutines flux_euler(), flux_rk2(), and flux_rk3() to use
   new update_flux() subroutine;

16ec922b2f Fix a bug introduced in 58cfb07e9ab54a0cb77775f78bdb9e6105c89309. 
- the order of flags CONSERVATIVE was wrong in the subroutines
   calculating numerical fluxes;

58cfb07e9a Return fluxes instead of their derivatives if CONSERVATIVE=Y. 
- if the flag CONSERVATIVE is enable, we need to return the numerical
   fluxes instead of their derivatives; the directional derivatives are
   calculated after sunchronization of the flux;

ed429e795e Add a subroutine to calculate numerical fluxes. 
- the subroutine update_flux() in the SCHEME module calculates
   numerical fluxes from the conserved variables; the calculated fluxes
   are then returned;
