Consider adding the non-minified js file in the zip archive

This would help tool repackaging the js file having access to a dev asset. See the relevant issue for CLJSJS packages.

I'm not sure if it belongs here or if I should make a separate issue, but I'd love the npm version to include the unminified version as well. I'm playing around with this using webpack and the sourcemap won't work, which is frustrating.
