webpack: bundle is now VALID.

[eglassman]

This seems to be due to webpack? Existing issue: webpack-contrib/css-loader#144

[eglassman]

In their discussion, they say:

Add to webpack.config.js
require('es6-promise').polyfill();

and it's now working!

[eglassman]

I'm not familiar with webpack. Does this make sense to you, @alltom?

[alltom]

Ah! Maybe I just have a much newer version of node than you. I'm running 5.0.0, so I don't need the polyfill. I don't think it hurts to add it, though, so we may as well.
