CSS updates

i changed the layout of this page a little bit. now it adapts to the size of the browser window… well, the minimum window size still is about 800px wide (if you wanna see some funny layout effects, try viewing the page in a tiny tiny window… ). i had to turn the menus on the left and right into “floating” objects. apparently (and this aint obvious) floating objects have to be placed before all other objects in the html source file (!)
