Removes depencency on babel-runtime.

Simplifies babel transform using "loose" options and removing some transforms. This results in a subset of ES2015 environment, but this source has been pretty careful to avoid the more novel features in order to support more environments.

The result for those using graphql via npm is fewer dependencies and less reliance on a modern JS environment, both good things when wanting to use graphql as a depencency in a client-side tool, like Apollo or Relay.

Fixes #414
