Subject: [PATCH] feat(code-style): Add a script to automatically format all
 changed files

If executed inside the repository it will run the default Contiki
uncrustify script on all changed .c and .h file. This could be added
as a Git pre-commit hook. See http://git-scm.com/book/en/Customizing-Git-Git-Hooks
