add node-resolver-mode recipe

This package allows you to start a process using [node-resolver](https://github.com/meandavejustice/node-resolver) in the root directory of the file you are working on. This process checks for `require('...')` statements in your nodejs programs and will install node_modules in the background for you.

The source for the package can be found at [https://github.com/meandavejustice/node-resolver-mode.el](https://github.com/meandavejustice/node-resolver-mode.el).

I am the author/maintainer of this package.
