Corrected the netgen setup file, which was missing the nfet 5V
native vt transistor in the list of transistors. Added an entry
to ignore the cell "condiode", which appears in schematics but
cannot be extracted (due to apparent lack of defining
characteristics). Corrected a comment in the magic techfile
(non-functional, no impact on use of magic).
