Fix document is not defined

[Redmega]

Unhandled rejection ReferenceError: document is not defined
at exports.default (/path/to/node_modules/react-motion-drawer/styles.js:24:33)

Faced an issue with this in another project, realized my mistake.

This fixes the ReferenceError issue. Don't see any other issues. With this change it's working in practice now.

I made the pull request as I am not sure what the process is for updating the npm package. Was hoping you could shed some light on that. Is it just directly tied to master?

[KyleAMathews]

There's a npm script for making a new release.

[Redmega]

Ah, I see them. Thanks. I would prefer to let you handle the releases and such, I don't feel up to that yet.

[KyleAMathews]

Cool — it's pretty easy with the script and all so whatevs :-)

[KyleAMathews]

And 2.1.4 is out.

[Redmega]

Sorry about that!

[KyleAMathews]

No worries! We're making good progress.

Question is, why is the render called with an undefined document? styles() is only used in the render() function. Does this have something to do with isomorphic rendering where document is not available on the server? Maybe we can solve this another way, instead of just sticking it in an if(document)...

[KyleAMathews]

Yes, it's for isomorphic rendering — there's not really an easier way afaik. It's if statements or putting any code touching document inside a function that's only called on the client e.g. componentDidMount.
