5e4c1ed078 Fix shunted diode footprints on encoder boards
The encoder boards (ATmega328P, Atmega2560, Apple2(2560) can accomodate
keyboard matrices with no diodes, by adding per-row diodes on the
encoder board.  For keyboards with per-key diodes (the typical use
case), the per-row diodes are not needed, and therefore the footprints
should be shunted by default, using a special shunted diode footprint.
When diodes are installed, the shunt can be cut with an x-acto knife.
Previous board revs had the correct footprint, but somehow the regular
diode footprint was substituted on the last release of each of these
PCBS.  The correct footprint has been restored.

5f27567db3 Modify to use DIP switch or jumpers
- Add combined DIP-switch/Jumper footprint to footprint library
- Fix Apple2-encoder and interface-ascii-atmega2560 schematics and PCB to use
new footprint.
