Two more website styles

As mentioned before the current website design doesn't look too good
in case there is only few content on a page, see
<URL:http://iwi.uni-sb.de/angeli/misc/auctex/multipage/>.

By trying to make the design a little more open, I came to the result
to be seen at <URL:http://iwi.uni-sb.de/angeli/misc/auctex/multipage-2/>.

The problem here is that the menu has too much weight compared to the
other parts of the page, the main content is not centered in the area
with the white background and it suspiciously looks like the old
corporate design of Hewlett-Packard.

Thus, I got rid of the box for the container and the menu in the next
iteration which can be found at
<URL:http://iwi.uni-sb.de/angeli/misc/auctex/multipage-3/>.  And this
is a solution I can actually live with.

Note that you have to use a Gecko-based browser like Mozilla Browser
or Firefox in order to see the rounded corners of the boxes because I
used a CSS tag not available in other browsers.  This is just for
prototyping and will be exchanged with a browser-independent solution
for the final design.

One remark about the last design: This is actually very cool because
the layout is based on em-units, i.e. it changes proportional to the
font size, whereas the other versions relied on fixed pixel values.
Suppose you are a visually impaired person and need to set a very
large font in your browser.  You can do this by typing `C-+' several
times.  Now watch how the results of doing this differ between the
multipage-3 and multipage-2 layouts.  (Of course, the multipage-2
layout can be implemented in the same way as multipage-3.)
