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.

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.
