Configure pre-commit tool for this repo

[webknjaz]

Rules:

1. DO NOT commit to master. ever.
2. ABSOLUTELY NO force pushes allowed for public non-feature branches.
3. For every feature, create a new branch matching name feature/<issue-number>-<feature-name>.
4. Submit every feature by creating Pull Request @ github, after that wait for review, fix issues, repeat until approved. If needed rebase the branch on top of master and re-push force it.
