Fixing RAM calculator and reduced actual SRAM usage - 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

Fixing RAM calculator and reduced actual SRAM usage - 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

Adding initial Teensy 3 support, compiles, but not fully functional yet. - 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
