Title: compatibilty with the node.js buildpack for installing node

This adds special support for using `package.json` for installing a specific version of the node when using [multibuildpack](https://github.com/ddollar/heroku-buildpack-multi) and the [node.js buildpack](https://github.com/heroku/heroku-buildpack-nodejs).
