Merge pull request #36 from bilke/pre-commit-checks

Enables configuration of uncrustify pre-commit-check.

Uncrustify is a source code beautifier. Enabling this via scripts/init.sh runs uncrustify before commit on the changed files and *suggests* changes to the code to be conform with the style guide.

This should enforce a common code style and reduce number of white-space changes and also improve the readability of the code.
