Implement UMD build scripts

[Morfent]

This allows redux-router to be run in the browser and hosted on CDNs. Redux-router is available in the browser as window.ReduxRouter.

Why is envify necessary?

[Morfent]

@It's useful if there's code here that relies on process.env being a specific value, but looking through it, it's not used at all here. Should I take it out or leave it in in case it does get used in the future?

[Scarysize]

Yeah, please remove it :-) We can always re-add it, if it´s ever necessary.

[Morfent]

Removed.

[Scarysize]

Hey, it would be nice if you could modify the package.json accordingly. So the UMD build can be served by npmcdn.com.

Take a look at the bottom section "Suggested Workflow" here: https://npmcdn.com/#/

@Morfent Are you still going to fix this?

[Morfent]

I will when I get around to it. I have other priorities i need to deal with first before i can get back to this.

[Scarysize]

Okay, thanks for the feedback. I will leave this open then.

[Morfent]

That should do it, I believe.

[Scarysize]

LGTM, @mjrussell could you give this a quick look, too.

[mjrussell]

Hm Im not as familiar with UMD. Do you need to add lib to the files now that its defined to include dist?

[Morfent]

I'm not entirely sure, since I've never published an npm package before. Checking the UDM files created when running npm publish, they seem fine. Here's the output from attempting to run npm publish, if it helps:

Looking at react-router-redux's setup seems to indicate we should - https://github.com/reactjs/react-router-redux/blob/master/package.json

[Morfent]

I added the list of files that react-redux-router uses in package.json.

[mjrussell]

Looks good to me

[Scarysize]

Nice!

[Scarysize]

I published a version with your update to npm.
