CDN, package.json, CSS Variables free

[jmas]

CDN is good place where polyfills can be.

You can add package.json to add npm support. Other developers can import your polyfill to page through browserify.

As you can see caniuse statistics - CSS Variables is supported only by modern browsers. So please add IE browsers support.

There is an npm package -- although if it's by the original author I'm unsure -- but it still creates multirange as a global variable, which is not idiomatic. Ideally, it should do some sort of detection to see if it is running in a CommonJS environment and assign to module.exports conditionally.

@jmas I doubt at this point this would be accepted anywhere as a polyfill, since the relevant syntax was removed from the spec due to lack of implementor interest :(
This in turn reduced my interest in maintaining this plugin TBH...

@markasoftware Feel free to send a PR for this and (assuming it works and it's not huge) I'll merge it :)
