Compatibility with Meteor v2

[pouya-eghbali]

I upgraded my project from 1.12.1 to 2.2 and it looks like the upgrade breaks this package.

I investigated the issue and it seems like on 2.2 the Babel.getDefaultOptions call in transpileWithBabel returns options with sourceMaps set to false. Adding a .babelrc or babel.config.json file to the root of the project doesn't solve the issue, as a workaround I added options.sourceMaps = true; under options.filename = path;.

I'm not sure if I'm doing something wrong, are there any babel or meteor configurations that solve this issue or setting the sourceMaps option in the transpileWithBabel file is the way forward?
