Pass CLI options to webpack

[IanVS]

As far as I know, there are some webpack cli options like --progress which cannot be set in a config file (maybe I'm wrong). If that's the case, it would be pretty nice if there were a way to pass these options to the underlying webpack. --progress is the one I'd really like, but making it more flexible could be good too. What do you think, is it possible to do?

Yep, some kind of progress would be cool.

This brings me to the idea to implement something like create-react-app with auto clearing the console and just display the latest stuff like

• build progress
• build errors
• test reports

and just clear the console between each state change.

Please have a look at #97.
