[Grml] Improved favicon

Hi,

a big thanks to the grml team. I just love it! A little of my love for grml is at http://darkride.net/grml/ Since the current favicon.ico doesn't scale that nicely I created a 16x16 one. Please have a look and copy one if you like it. I don't claim any copright, you can even omit credits.

cu, Christian
