Moved mounting slots from keyboard PCB to aligners - This allows the PCB to sink below the mounting brackets. The aligner height can be adjusted relative to the mounting brackets using spacers. - changed futaba aligners to use cherry stabilizers. - bumped rev number

SOL keyboard adjustments - Fixed position offset error in first three rows of the SOL keyboard - moved key matrix interface connector to bottom of board so the parallel output connector can be at the top of the keyboard. - Adjusted size of mounting slots to accommodate #6 screws. - ongoing clean up of traces.

Update Sol keyboard to 1.5 (Minor changes) - Fix title in Schematic - Slightly enlarge center post hole on switch footprint, to allow a bit of tolerance. Very tight tolerance makes the keyboards hard to assemble.
