Add fetch's clone function to Request and Response prototypes

Browse Source 
Summary: Fetch includes a cloning function that was not included in the React Native fetch.js. This adds it in so that cloning is available on responses from fetch calls in React Native. The code is taken directly from [fetch](https://github.com/github/fetch/blob/master/fetch.js) on Github.
