Title: geda-gaf and pcb: Patch pcb crashes; Fix geda-gaf's pcb directories.

I recently attempted to use pcb and geda-gaf and ran into some issues, which these changes resolve. I am not familiar with the packages, so I am sharing these changes in the hope that someone finds them useful.

In particular:
* pcb crashes when attempting to show the netlist window if no netlist is loaded
* pcb crashes when attempting to display preferences when library-newlib is not set
* gsch2pcb uses data directories relative to geda-gaf's cellar path, not pcb's path
