Redo the "pin 1" dots so they are circle graphcs and not pads, which
don't seem to render in most Gerber files.

The Kicad default footprints seem volatile and unreliable. Going
between two machines that both have "Kicad 5.0.0" installed results in
incompatibilities because KiCad has renamed their footprint libraries.
Also, for some reason it's going to Github to get footprints instead of
using local copies.
Copy every model and footprint we use into a local tomu-fpga.pretty.
This lets us ensure we can work offline, and also allows us to modify
footprints, e.g. by adding a "Pin 1" marker.
