- Also updating usbMuxUart header with most recent keyboard defines

- It's possible to get even more, but this is probably as far as I'll go
- PROGMEM is really annoying to use, and makes the code look like ass
- Now the Teensy 2++ should have enough RAM to use PartialMap easily

- Easier to debug USB initialization

- CLI now works with hex or decimal numbers
- Hex requires 0x (technically just x would work too)

- Changed static variables to const that should have been const
- Updated CMake files to prepare for MCHCK custom bootloader
- Changed the USB ID numbers and ID number for bootloader
- Only generate DFU or Teensy binary image, not both
- Fixed RAM and FLASH calculator
- Added missing license in delay.c/h (much of it was taken from Teensy source though I've changed a bunch of it)
- Prepared mk20dx.c for upcoming bootloader addition
- mk20dx.h cleanup
- Reduced the MCHCK based flash size for the application image (bootloader changes requires more flash space)
- Fixed bugs in macro.c
- Added keyHold cli command
- Added show pending events debug message for PartialMap macro module

- Cleaned up Macro and USB callback naming
- Added security jumper for automated reload (MCHCK based only)
- Added additional LED position

- 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

- Sending characters to the UART before it's ready would overflow the buffer causing it to hang
- Added a check to make sure the interface is ready before starting to send characters
- Removed the incorrect check for the usbMuxUart to make sure usb is ready before sending over the uart

- The UART out may be useful for Bluetooth keyboards at some point
