Fable bindings for Fetch API

The Fetch API provides a JavaScript interface for accessing and manipulating parts of the HTTP pipeline, such as requests and responses. It also provides a global fetch() method that provides an easy, logical way to fetch resources asynchronously across the network.

See: https://developer.mozilla.org/en/docs/Web/API/Fetch_API
