Title: don't recommend checking in node_modules

Updating some old docs. /cc @zeke

The existing recommendation (check in deployable packages) was the best idea with node 0.4. These days, we see a lot of Heroku customers having issues due to this practice and generally recommend against it in favor of shrinkwrap.
