- Changing default name from defaultMap.kll to scancode_map.kll - Old name of defaultMap.kll will still work (and is the final fallback) - Updated all the main projects to use the new name - Updated BETKB (not entirely finished, but mostly complete) - Added sub-use of interconnect scancode cache for converters - Added infinity_led.bash No behaviour changes, just restructuring.
