title: Npm package.json inheritance
body: <p>Is there a mechanism in npm like parent pom in Maven. 
  The goal is to have a common base configuration for scripts, dependencies, devDependencies. 
  Not based on templates like yeoman or so, but based on a parent version. So that, any project that changes his parent version gets the changes in this parent automatically.</p>
  
  <p>Can you point me to hints to achieve this?</p>
  
  <p>Thanks!</p>
