Create SBG bundle

[darind]

Currently the static binding generator has a couple of NPM dependencies that need to be installed prior to using it:

• "babel-traverse": "^6.26.0"
• "babel-types": "^6.26.0"
• "babylon": "6.4.5"
• "lazy": "1.0.11"

Those dependencies are installed by the NativeScript CLI when adding the android platform which, depending on the network connection, might considerably slow down this operation.

As a possible improvement we could use webpack to create a single executable bundle (js_parser.js) that will be included into the runtime package.
