Website update

The appearance of this website just changed, as you perhaps have noticed.

I did this today in the framework of updating the Atahualpa theme from version 3.3.3 to 3.5.3. Big action including vanilla WordPress test installation, PHP code changes, manual database changes etc. Furthermore, this update introduced some incompatibilities regarding my existing CSS code. So I had to tune this manually, too. While doing so, I optimized the menu structure and made use of the new customisable WordPress3 menus. And I took the chance to make the page look cleaner. Perhaps better. Hopefully :-) I like the blue. But I would have liked green. And pink? Jan said blau = seriƶs. Whatever..
