Title: fallback to default region (& endpoint) from environment.

This makes amazonica fallback to the region endpoint specifued by the ``AWS_DEFAULT_REGION`` env var if it's specified and not supplied in the credentials map. This allows 0 arg invocation of various fns when you don't want ``us-east-1`` as your default region.
