Increase node version requirement

[wdavidw]

Hi Brian,

Could you update the 'package.json' file to allow for node version greater than 0.4.x, the git version is `v0.5.0-pre' and don't pass. Something like

"engines": { "node": ">= 0.4.x" }

should work.

Thanks

Thanks for the heads up. Done! I didn't do a version bump (just an unpublish and publish), so npm uninstall, then install again.

Great, thanks for speed
