Add daemon.node to npm

[rgrove]

daemon.node looks great, but it'd be even better if it were installable using npm: http://npmjs.org/

Having an npm package for daemon.node would make it possible for my own apps to pull it in as a dependency seamlessly without requiring the user to hunt it down and install it, which is a must for me.

I believe substack did this already, but it was never merged into slashed's repo. See their fork at substack/daemon.node.
