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.

It's much cleaner if we put power pins on one side and signal pins on
the other. This removes the ratsnest that was building up.

Add a crystal, so we can test to make sure it works.
Also add a second regulator dedicated to VCCPLL in an effort to
cost-down the capacitor and large components that shouldn't be
necessary.

For some reason, this pin was listed as a `power output`, which does not
appear to be the case. Due to this error, the DRC would fail when using
a regulator directly connected to the pin.
Mark this pin as a `power input` to fix this, since it's really where
power goes into the chip.
