Deploy process broken due to npm auth issue

[Edo Rivai]

Receiving the following message in Travis on build 406:

NPM API key format changed recently. If your deployment fails, check your API key in ~/.npmrc.

... and later on ...

npm ERR! publish Failed PUT 401
npm ERR! code E401
npm ERR! You must be logged in to publish packages. : react-media

@mjackson could you take a look?
