IMPORTANT: Corrected couple of bugs

[arango]

• mod_ncparam.F: Added missing END SELECT to the metadata for the adjoint sensitivity of inert tracers. Many thanks to Brian Powell for bringing this issue to my attention.

• main2d.F: Moved the updating of time index iic(ng) to be bottom of the time stepping:

  !
  !-----------------------------------------------------------------------
  !  Advance time index and time clock.
  !-----------------------------------------------------------------------
  !
              DO ig=1,GridsInLayer(nl)
                ng=GridNumber(ig,nl)
                iic(ng)=iic(ng)+1
                time(ng)=time(ng)+dt(ng)
                step_counter(ng)=step_counter(ng)-1
                CALL time_string (time(ng), time_code(ng))
              END DO
  
            END DO STEP_LOOP
  

  I corrected this bug some time ago in my research code, but I forgot to fix the distributed code. Anyway, many thanks to Bradley Reed for ​reporting this issue.

The change to mod_ncparam.F was done incorrectly. Many thanks to Brian Powell for bringing this to my attention.
