c13672b408 Multiple fixes for keyboard PCB 
- in combined CherryMX/futaba footprints, moved cherry pads down 1 mil and
futaba pads up 2 mil, to reduce risk of shortin of LED pads with futaba pad.
Adjusted all aligners accordingly

- Fixed centroid for combined diode footprint and adjusted PCB placement on
classic and SOL keyboards accordingly.

- Moved SMT pads in combined diode footprint to top layer, so pick & place file
will be usable.

- changes to futaba stabilizer design.  Longer post adapter passes through slots
in keyboard and aligner.

- Changed futaba post thickness gauge from board outline to a slot to improve
tolerance.

- Moved spacebar stabilizer bending guide to edge of PCB, in order to make it
more useful in bending PCBs.

- Changed Apple II mounting slots on classic keyboard from horizontal to
vertical orientation, to accommodate the different spacing offets due to the use
of spacers in angled mounting threads.
