React is undefined when loading React with a script tag

[ronaldborman]

When I explore a new library, I like to use a webpage, load the library and all dependencies with script tags and write example code in a script tag.

In React-Formly 0.0.4 this setup worked, but in 0.0.5/Master I get an "Cannot read property 'createClass' of undefined" error on line 16 of Formly.js ("var Formly = React.createClass"). While the browser indicates that React is undefined, React is available on the global object (a.k.a. window).

I suspect that this is a side effect of commit e943db6. Unfortunately my knowledge of Webpack is limited, so I cannot suggest a comprehensive change.

I realize that the use case for using script tags is limited (essentially only exploration), but I think it's valid enough to include it in React Formly.

I personally think that being able to play around with it in the browser as a script tag is quite valuable and I would say it's a requirement for this library. Do you think you can make this happen @Astrism?

Makes sense to me, I should be able to look into it soon.
