- Commenting cleaned up - usb_keyboard_debug is not finished yet in terms of cleanup (needs DEBUB_PRINT #ifdef's) - Added LoadFile script generation - Formalized KeyIndex and USBKeys data containers - Split parts of scan_loop into Macro, USB, and main.c - Added interface to USB modules - Added interface to Macro modules - Added proper Debug module enable/disablesimple
