	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.
