We decided to split the media webpack config into it's own file. The
main webpack config then combines this file with the packages config.
Include vendor scripts by copying them. We copy the minified files if
they are available. If they aren't available we minify the original
files ourselves.

* Minification is done by uglify, so disable that in the media build.
* The webpack boilerplate has changed, which explains the changes in the build files.
* `ModuleConcatenationPlugin` is enable by default for production builds so we don't have to specify that ourselves.
