core: Change external interrupt code to NOBLOCK so it wont mess with USB libraries.
DigiKeyboard: Added print/println stuff so you can easily type in strings and numbers and bits like that. scancode-ascii-table could be compressed better, it has a bunch of zeros in it currently, all near the start!
