Offer an embedded mode for system-config-printer

This is used in Mageia for integrating system-config-printer
with the Mageia Control Center.

It was originally written by Tiago Salem of Mandriva for replacing
PrinterDrake in the Mandriva Control Center for Mandriva 2009.

It has been mantained by Mageia for successive versions of
system-config-printer.
