Allow configuration of ES6 transpilation and polyfills

[indianscout]

The current code does only browserify the module without polyfills and transpilation of recent JS/ES6 features. This could easily be achieved by providing the according babelify options browserify().transform(). The following quick and dirty workaround in index.js, line 42 works in my case but is very specific for my use case:

var b = browserify(
  options.file, 
  {standalone: options.namespace}
).transform(
  "babelify",
  {
    presets: ["es2015"],
    plugins: [
      "transform-class-properties", 
      "transform-object-rest-spread", 
      "transform-array-from"
    ]
  }
);

The best would be to include an cli option (-b, --babelify) with a json file containing the babelify configuration (similar to -e).

-b, --babelify option added. @indianscout you mind testing (I only did super simple test). If all looks good, I will publish change to npm. If you find any issue, you mind fixing and making pull request?

I'll do some more testing. THX for the quick fix :-)

Test with -b and --babelify option looks good (also with relative path):
