Redo the numbering for the dbg pins. While we're at it, add some silk
to the Raspberry Pi header so that we know what we're looking at.

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.

Some components were getting added to the BOM that shouldn't have been,
and some were missing from the pick-and-place file.
Update the `Placement Type` to be accurate according to assembly.

Move some vias around to get the 5V plane more breathing room. Add a
small pour to give more copper and stabilize the net.

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.

Add a note indicating the PCB thickness and color.
Also, move the drill origin to the lower-left corner, to aid in machine
assembly.

Add more silk, indicating website and other info.
While we're at it, move some traces around to give more copper area, and
drop some more vias to improve ground performance.
