This modifies the Postscript printer to be able to insert a pipe in between the Postscript generation

and the transport addon. The actual command use as pipe is retrieved from the PPD that can be selected
at printer creation time.

Currently PPD selection is not shown (as the PPD directory is not available) and therefore the pipe
will not be inserted.

This still needs a bit of TLC, so hope to commit the last changes to fully support this later this week.
