[v2] outstanding small issues

[jquense]

Just documenting stuff as i'm noticing it and trying to get stuff working so I don't forget.

• babelrc.js support isn't right
  • gatsby mutates the babelrc, which isn't a problem for json, but a big deal for .js since the plugins keep getting added over time (need to clone it)
  • Something weird is happening with 'cacheDirectory' i think related to the mutation

Yeah I want to move modifying babelrc to redux like everything else.

Anything that needs addressed here still @jquense? We've done a lot of work on babelrc + have issues for remaining work. Do remember what the cacheDirectory issue was?

I think we got this all addressed with the reduxification of the babel config :)
