Add babel-core as a dependency

[philippotto]

Despite having babel installed as a global dependency, I had a weird error when trying to run this project (on Windows):

> node server

webpack: bundle is now VALID.

Even though the output says that the bundle is "VALID", opening localhost:3000 yields another error. Adding babel-core as a dependency resolves the issue for me.

I got the same error and installing babel-core independency helped !
