- Easy to fix if I remove the macro engine...

- Commenting cleaned up
- usb_keyboard_debug is not finished yet in terms of cleanup (needs DEBUB_PRINT #ifdef's)

- 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/disable

- Loader script generation isn't complete

- Added better string handling and canned messages
