FYI - this is the bit that redirects loomio.org to www.loomio.org, and it also redirects loomio-clone.herokuapp.com to clone.loomio.org. I'm guessing you already knew this, but yeah, you'll probably want to make sure that the functionality at the end of this all is intact, because otherwise you may end up with non-canonical addresses (e.g. people being able to go to both loomio.org and www.loomio.org when it's the same thing).
