title: Procfile has no extension so it doesn't associate with an app?
body: <p>This is just a small annoyance but the Heroku Procfile does not have an extension.  This causes me to have to select an application for it, each time I double click it.</p>
  
  <p>Normally after selecting an application for a file, the system remembers and I don't have to do it again.</p>
  
  <p>I'm wondering if I can just add a random extension and it will still work?</p>
  
  <p>Something like</p>
  
  <blockquote>
    <p>Procfile.procfile</p>
  </blockquote>
  
  <p>or</p>
  
  <blockquote>
    <p>Procfile.txt</p>
  </blockquote>
  
  <p>Also because it has no extension there is no icon associated with it as well if this is not obvious.</p>
