Make dropdown inside the docs to link to "inside the docs" for other languages

[jgeewax]

The dropdown you see here: http://googlecloudplatform.github.io/gcloud-node/#/docs, when switching, links to the other-language-equivalent of http://googlecloudplatform.github.io/gcloud-node/

Could we have it link inside the docs of those other languages?

ie:

• Python: http://googlecloudplatform.github.io/gcloud-python/latest/
• Ruby: (we don't have this link yet, see Add /docs/latest URL? google-cloud-ruby#183)

Updated the Python link for now.

The Ruby URL should be http://googlecloudplatform.github.io/gcloud-ruby/docs/latest
