WIP checker

The brand new WIP checker checks for commit messages starting with "WIP" and prevents you from pushing the corresponding commits.

This can be ignored with an option :

git push --no-verify

This hook is language-agnostic.

Enable it like this :

git config --add hooks.enabled-plugins wipchecker

You may want to enable it globally, like this :

git config --add --globals hooks.enabled-plugins wipchecker
