- clang.c includes necessary functions to make clang compiler work (tested on teensy 3.1)
- Added support code to generate a compile_commands.json for clang-tidy
  * Updates the symlink whenever cmake or make is called (Unix OSs only)

- If dfu-suffix is not found, a warning is given and the binary is not signed
- Unsigned binaries are still ok with the latest version of dfu-util

- Currently builds larger binaries than gcc (RAM)

- 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
