Implemented an idea from Staf Verhaegen to have "labels" options 

"port" and "noport" in the cifoutput section to distinguish
between layer:purpose pairs for port text vs. other kinds of
text.  This allows a closer correspondence between GDS read and
write.  Note that the port writing is currently only in the GDS
write routine, not in the CIF routine.
