publish to npm

This has not been published to npm in a while. I'm interested in the fixes to exception handling for compatibility with mkdirp. Currently I've got a link to this github repo in my package.json, but I'd rather use a semver.

Agreed, that would be real nice! All it takes is a quick commit and npm publish. Otherwise, the docs on webpack.github.io are wrong as the example using memory-fs is broken.
