[streams] Es5 distribution (#432)

With ServiceWorkers growing in popularity, we would like to start prototyping a server-side execution environment for ServiceWorker code. This includes `ReadableStream`, which is now available in Chrome Canary. The reference implementation would fill this need. However, there does not seem to be any current version in the npm registry.

Therefore, I am proposing to publish a transpiled ES5 version of this reference implementation.

This PR sets up babeljs in a prepublish hook. It is little more than a POC, but is confirmed working by publishing (and unpublishing) to npmjs.org.
