Previously we hadn't been doing the mapping from MED -> GLC when CISM
was running in NOEVOLVE mode. This was a problem because this downscaled
SMB is one of the main benefits of running CISM in NOEVOLVE mode.

Resolves ESCOMP#426. See that issue for details.

One other change here is that I skip GLC -> MED in NOEVOLVE mode. I
*think* that's a safe thing to do, but I'm not 100% sure of it.

When this was based on run_glc, NOEVOLVE cases were failing like this:

This fails in the InitializeRealize call to export_fields, and
specifically in this:

       ! Set scalars in export state
       call State_SetScalar(dble(get_nx_tot(instance_index=ns)), flds_scalar_index_nx, &
            NStateExp(ns), flds_scalar_name, flds_scalar_num, rc)

So it seems like we need to have GLC -> MED in the run sequence for
initialization to work correctly.
