Use window.document

Allows for webpack server rendering (when the top-level document is not defined).

Potential fix for #474.

Downside of this is that it'll break even more on Node where window doesn't exist... Maybe try a check like window ? window.document : undefined ?

You can use hack to get global object on an environment:

var global = (function(){ return this; })()

it is function's feature, when it doesn't has context, it has global context

[Rycochet]

Doesn't work with "use strict" - so a bad idea to try and rely on undefined behaviour. Technically (window || global) will get the right one, but we're only interested in window, as the code referencing it is not for use in Node etc.

@Rycochet good call. I added the check.
