* Javascript Generator: small sanitization changes
Sanitize module name, do not sanitize description.
If we set the project name to "@myorg/mypackage" (scoped package[1]), running `npm test` will fail, as it will generate faulty code due to the module name including the '@' symbol, which is not a valid JS identifier.
Additionally, we don't need to sanitize the description - spaces and special characters are fine. We just need to make sure they are escaped, which we're already doing by invoking escapeText() on line 329

* update JS samples
* Add build script and remove babel
This change adds a build script which uses babel to transpile generated es6 source to es5, such that it can then be used in node projects or published as a package to npm. The `babel` package is also removed as it is deprecated, and superseded by `babel-cli`.
