Docs project migrated

Reminder -- the docs project is now at

https://github.com/ansible/ansible-docs

If you have any docs changes, please submit them here to the files in
the "rst/" directory.

It works bascially exactly the same as before, but the
github/ansible.github.com project now just contains redirects to the
new website, which is http://ansible.cc

The redirects will probably be up forever.
