Sean Cross 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.

Sean Cross e48d836372 pcb: remove usb silk, add more 5V vias 
Add more 5V vias near the 1.2V regulator, and replace a manual trace
with a copper pour.  This will increase the amount of copper going to
both the 3.3V and 1.2V regulators, which should improve stability.

While we're at it, remove an errant silk artifact on the USB connector.

Sean Cross 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.
