Modified the handling of missing pins (again) such that netgen 

continues to allow missing pins to match unconnected pins, but
*only* on subcircuits below the top level.  This essentially forces
layouts to separate merged pins with metal resistors, although
there should be an option in magic's ext2spice routine that allows
"equiv" statements, when declaring equivalence of two ports, to be
replaced by a zero volt source or zero ohm ideal resistor.
