Initial preparations for automated deployment

The big thing here is deploy/README.md.

It felt like overkill to me for two packages, but to each their own. The `forever` dependency is more helpful to be installed globally (with the `-g` flag) so that you can run it from outside the project directory, especially if you're using a deploy situation where the project directory is a symlink that changes (we ran into this on team FOIA).
