Summary: Detects if the user is on Node or io.js 1.x and prints a banner explaining how to upgrade. We probably should link to more detailed upgrade docs so this is just a start. I also added a function to format banners that is kind of useful. Addresses part of #1737  Closes https://github.com/facebook/react-native/pull/1824 Github Author: James Ide <ide@jameside.com>
