Incorrect logic in get_ngfld

[arango]

Corrected a bug in file get_ngfld.F around line 193. We need to use n_vdim instead of n_dim in the DO loop:

!
!  If Nrec=0, input file is not CF compliant, check variable dimension
!  to see if the dimension contains the "time" string.
!
            IF (got_time.and.(Nrec.eq.0)) THEN
              DO i=1,n_vdim
                IF (INDEX(TRIM(var_Dname(i)),'time').ne.0) THEN
                  Nrec=var_Dsize(i)
                END IF
              END DO
            END IF

This only occurs when input file is not CF compliant with the time dimension.

I also updated several of the CDL files to be CF compliant.
