- McHCK uses FLL instead of the PLL for USB (startup, not usb init)
- Added optional debug for the pjrc USB module
- Cleaned up compiler flags

- For potential bug fixes
- Not copied verbatim, some additions were left out

- reset   -> Simulates power cycle (Not yet compatible with AVR)
- reload  -> Sets the device into firmware reload mode
- led     -> Toggles the error LED
- version -> Displays detailed version information (additions to CMake files was necessary, might have broken Windows builds...)

* Initial cli code

- Also a bit of general house-keeping

- CDC Output seems to be working
- USB Keyboard output has not been tested, but is "ready"
- UART and Timers have not been tested, or fully utilized
- Issues using Timer 0
- Initial template for MBC-55X Scan module (only module currently compatible with the arm build)
- Updated the interface to the AVR usb module for symmetry with the ARM usb module
- Much gutting was done to the Teensy 3 usb keyboard module, though not in an ideal state yet
