title: Depend on a branch or tag using a git URL in a package.json?
body: <p>Say I've forked a node module with a bugfix and I want to use my fixed version, on a feature branch of course, until the bugfix is merged and released. </p>
  
  <p>How would I reference my fixed version in the <code>dependencies</code> of my <code>package.json</code>?</p>
