Removed all the old things specific to the Sink and its programming jig.
Removed (I think) all references to the PD Buddy Sink, replacing them
with PD Buddy Dev. Reorganized repository for just one KiCad project.
Set the _KI_LIB_GIT path to point to a local copy of the kicad-library
Git repository. Then this project will pick up the Git libraries
instead of the system ones.
