There must be a way to provide Babel options

[s-panferov]

Hello! Thanks for the awesome project.

I found the feature #475 with optional babel support very useful. But it seems incomplete to me, because there must be a way to specify Babel's options. Existed solutions like https://babeljs.io/docs/usage/babelrc/ don't work (or I'm doing something wrong).

Maybe we can offer the second extended form of the externalTranspiler option?

"externalTranspiler": {
    name: "babel",
    options: {
        /* babel options goes here */
    }
}

Or maybe there is a way to make .babelrc work?

I like the simplicity of this 🌹

How does this work? I set this, I have babel installed in my node_modeuls dir, yet no transpilation with babel hapens. Also, the options are not available, I need to use babel plugins.

@tomitrescak personally I've never used this option so can't be much help. With the TypeScript compiler getting a transformer based emitter soon, we wouldn't need to offload heavy plug-gable emitting to babel hopefully 🌹

Still docs https://github.com/TypeStrong/atom-typescript/blob/master/docs/faq.md#can-i-use-an-alternate-transpiler

It calls Babel on the emitted result before writing it to disk. This was a bit of a hack to get let for loops working pre-1.8 and it includes babel 5. Look at the referenced PR.
