Please .npmignore anything that's not needed for production

[MarcDiethelm]

I'm pretty sure tests are not needed in production. :) They just bloat project dependencies, install time, use bandwidth, etc.

You could either use the package.json files property to whitelist files for production or .npmignore to blacklist unneeded ones.
