6a392e57d2 pcb: rework pcb with correct footprints, add tvs diodes
Add TVS diodes, so we make sure they work.

Also, rework the PCB so that the clock actually functions now.

1f878d4fe6 hardware: footprints: fix SOIC-8
This footprint was completely incorrect.  The footprint appears to be
for a SON-8 not a SOIC-8.

37ff812b49 hardware: pcb: replace "text" with "value" for buttons
Previously, we used text to display the "5" and "6" designators for the
physical buttons.  Replace this with a value of "5" and "6", and remove
the extra text.

Additionally, display "SW??" under the switch, to make hand-assembly
easier.

Do the same thing for the "Reset" button.

9639d75a11 releases: remove evt1 and evt2, and rename evt3 -> evt1
evt1 and evt2 were never produced.  They also would never have worked,
because the USB connector was drawn mirrored.

Remove these and replace them with a single `evt1` that was actually
produced.

This reflects the fact that the `evt1` boards actually say "EVT1" on
them.

Add more 5V vias near the 1.2V regulator, and replace a manual trace

f3315b58d8 pcb: add our own copies of 3d models and footprints
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.
