title: Invoke grc terminal colorizer on ALL commands implicitly
body: <p>I love the grc colorizer for the terminal. However I have to explicitly prefix anything I want colorized with:</p>
  
  <pre><code>grc --config=conf.mine
  </code></pre>
  
  <p>Is there any way to have it automatically applied to everything you input on the command line (so that potentially I don't even need to know what grc is)? Perhaps using shell hooks, if a better alternative doesn't exist?</p>
