Dave fb28dd34fc Multiple fixes to classic keyboard for fit and build ease 
- remove material from PCB to allow keyboard to fit in Apple II case

- enlarge center hole on cherry MX footprints slightly, to 0.160" to allow
slightly more tolerance, which eases assembly.

- include holes for LEDs on futaba aligner

- include extra pads on main PCB for LEDs with futaba keys

- Add LED on LINE FEED which maps to REPEAT/CAPSLOCK on Apple II keymap
