README.rst page doesn't mention the pub/sub client or bq

The project home page provides examples of some of the API features like datastore, but doesn't list them all. This leads to an initial impression that the library doesn't support pub/sub or bq when it does. It's not obvious until you dive into the documentation.

Thanks for noticing @ajessup! I'll get on this ASAP.
