Add support for Git Hooks

I’d love to see support for the git hooks. Some of these hooks are:

• pre-commit
• prepare-commit-msg
• commit-msg
• post-commit
• post-merge
• pre-push

And others. They can be found via this resource and this resource in a more “plain-english” way.

I’m willing to implement this functionality, however, I’m wondering what the API should look like. Do we want to look for the related files and run them with spawn? Do we want to make pre-X and post-X actions and utilize a plugin-like system and provide this logic as an additional package? What do we think?

Sounds like a plan

I’m ok for hooks if they get internals of git like refs. But we need to come up with an API that will much the current architecture of passing stuff to each function.
