Ability to extend options passed to include configFile

[code4cake]

For some reason when I have a babel.config.js on the project, the babel() does not pick up that file, only when I change it to a .babelrc it works.

Possibility to add a configFile option to specify the path of the babel config file to load.

Do we need a PR for this, if not already present?

@andywer cool I'll take care of it. Thanks

just an update: I'm still taking care of this, it has proven a bit more complicated than I thought, but still hacking on it
