Update for pd-buddy-python 0.5.0

With the new API changes in pd-buddy-python 0.5.0, a few fixes were
necessary to make the GUI work without errors again.  Among these were
creating a SinkConfig object with the new attributes, and adding list
rows for PPS APDOs.  Coming up next: voltage range support!
