Move new torstatus (atlas?) to git

I've spoken to hellais and it would be nice if we started moving the new (third) TorStatus to tor's infrastructure. The first step would be to move it into tor's git repo.

This looks like it'll be non-trivial since multiple projects are subdirectories in the 'hellais.github.com' repository so my guess is that keeping history will be a no-go. That said, maybe I'm misunderstanding GitHub or Sebastian knows some gitfu to pluck it out.

Also, it's confusing to keep calling each new incarnation 'TorStatus' (this is the third one), so Karsten and I have proposed renaming it to Atlas. We'd then also host it under 'atlas.torproject.org'. Other suggestions are welcome.

Assigning to hellais first for approval and a description for the git repository.
