Fixes #22

Each (dfu) interface may have more than one a ltsetting each with their own index and name. According to the DFU_1.1 pdf section 4.2.3, "* Alternate settings can be used by an application to access additional memory segments. In this case,
it is suggested that each alternate setting employ a string descriptor to indicate the target memory
segment; e.g., 'EEPROM'." Whether or not we end up using multiple memory segments it is still good to have a descriptive name incase there are other dfu devices connected.

Edit: Fixed previous indentation

cmake -DREFRESH_KLL=1 ..

- Added AddModule CMake function which simplifies specifying module requirements

- Currently builds larger binaries than gcc (RAM)

- Not ready yet
- Will require some more changes to Lib/mk20dx.c

- Bootloader doesn't build correctly on gcc 4.7.3 (LTO issues)
- Even disabling isn't good enough
- 4.9.1 is known to work on Arch Linux

- Added layout files for 50 key and kishsaver
- Not yet working (some USB issues on AVR to debug)
- Fixed an OSX issue when building AVR
- Cleanup

- Automatically downloads the kll compiler if not found
- Added capability files to each of the module that currently have them
- Split modules.cmake so kll.cmake could influence build targets (also needs info from modules.cmake)
- Updated .gitignore for kll compiler directory
- Added documentation on how to manipulate layouts using CMakeLists.txt
- Cleanup of old layout files

- 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

- 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

- Lots of code cleanup for the intialization of all arm chips
- Added more gcc flags to help with debugging linker and memory map
- Fixed UART initialization for the smaller MCHCK mk20dx128 (different pin mux)

- Basic compilation and loading is working
- LED can be turned on/off
- USB not yet working

- Added executable detection script
- Build will still work fine if ctags isn't installed

- Tried to add auto cmake reset...so far unsuccessful
- Ported MBC-55X (was used to test compilers)
- Disabled in-source builds, to prevent CMake from shooting itself in the foot.

- Uses an internal database of microcontroller sizes

- Only one file to edit now
- Compiler architecture automatically detected based off of chip target
