  addPopUpLink
  opens all links with a certain class (launchpopupwin, launchpopupimpressum) in a pop-up window
  
  It’s always worth remembering that a visitor to the site might be using a browser that
  doesn’t have JavaScript support. Or maybe the browser supports JavaScript but it has been
  disabled.
  
  This JavaScript code was written in a proper way which means that the site will
  still be navigable by users who don’t have JavaScript. The site (popup functionality) degrades
  gracefully, meaning that the functionality may be reduced but it doesn’t fail completely.
  
  The problem lies with inline event handlers. Using an attribute like onclick in the markup is
  just as inefficient as using the style attribute. It's much better to use a hook, like class or id,
  to tether the behavior to the markup without intermingling it.
  
  This is what this Script does.
