webpack multiple config exports

[hiousi]

I'm working with a lot of locales. I saw that latest versions of Webpack can run with multiple configs exports. It can help to build a lot of locales in one quicker run than building with one webpack process for each locale. It is quicker because all common assets are not build for each locale, it could be very powerfull in case of a complex config with a lot of loaders and plugins.

Yes great, but it does not work :( translations are replaced by the last locale in all outputs. So I made a small repo to try and test this method.
