Provide option for removing webpack comments

[josh-asi]

Hi,

I love qExt but I'm just wondering if it was possible to add a minifier plugin when building for 'production' mode. I'd love to have a minified version of the files without all the auto-generated webpack comments.

Thanks

is there a way to change default 'development' mode for webpack? maybe take it from qext.config?
