Hmm, I probably didn't make this very clear. Everything from the class
extender could also just be added to applet. It makes sure every applet
can handle extenders. ExtenderApplet is a very simple applet that does
little more than this and functions mainly as host applet for a detached
widget.

That function can just access config() or sourceApplet() to obtain
usefull information. But maybe a mime type like approach makes sence,
I'll think about it.
