User and Repository as env variable for hooks

[misery]

Issue description

I develop a custom hook [1] for Mercurial and Git (experimental). It works for Mercurial really good with SCM-Manager and I tried git now. But it seems SCM-Manager do not provide env['REMOTE_USER'] and env['REPO_NAME'] to a pre-receive hook like it does for Mercurial.

So please add REMOTE_USER and REPO_NAME to git hooks, too.
