Create a set of config for minify = false

There is a [bug in minifyify](https://github.com/ben-ng/minifyify/issues/49) that prevents additional source map specific options from being passed in if minify is set to false. I forked the repo and spent a little time trying to figure it out but didn't have a lot of luck. I will update the code as that issue moves though.
