Add google v3 url signing for business accounts

Instead of just passing along your key as a query param, you must pass
along a SHA1 base64 encoded version of your query url as a `signature`

with the secret key and client id.

I needed to modify the google constructor to take api key and client_id,
and I also made the api key optional (which it already was, you just
needed to explicitly call it like `new(nil)`.
