  Hey @roll, please review the current work when you are able

Webpack is used for bundling profiles because it was the cleanest solution, SystemJS required hacking the json loader.

Tests are currently bundled with the module with webpack, so they can be easily shared with the node tests. Currently they can be seen by opening test/browser/index.html, I had an issue using phantomjs, specifically this one https://github.com/ariya/phantomjs/issues/13895. Also porting the tests is still in progress.

Also, addresses #54
