Support MultiCompiler / MultiStats about friendly-errors-webpack-plugin

[richardscarrott]

@DylanPiercey you'll need to apply the plugin to the the multi compiler returned from webpack, e.g. https://github.com/60frames/react-boilerplate/blob/master/server/routes/webpack.js#L20

const multiCompiler = webpack([config1, config2]);
multiCompiler.apply(new FriendlyErrorsWebpackPlugin());

Hi @richardscarrott, I'll accept any PR with tests 😄
Thanks for taking the time to document this issue!

What does the config look like to use this with a multi compiler? Do I add the plugin to both compilers?

[richardscarrott]

Okay, I've discovered applying the plugin to both compilers separately doesn't really work because the console may read 'DONE' because the most recent compilation succeeded but it obviously doesn't take into account the other compilation which may still be in an error state.

Would you be open to a PR for this?
