Support Config.node false value

Resolves #209.

I'd also like to mention the possibility of creating callable classes even though I feel it's rather hacky. Something like this could also be used for #222 (though that one could be resolved without weird hacks by introducing a breaking change and bumping the major).

@SuperOleg39 thank you for the PR and @opl- thank you for the really helpful review/thoughts. I don't use webpack day to day any more, so am reliant on suggestions as to what direction it should take longer term. I agree with @opl- 's thoughts about potentially confusing UX. What do you both think as the best option out of those that are proposed above?
