Small page update

Today I slightly changed the page style, to make it better readable.

The font is now bigger and Georgia (Tahoma was ugly, in particular in italic mode); the lines now have more spacing inbetween and the background color now is a gentle grey, which should be more comfortable for the eyes than the clean white was.

Some more minor changes are worth looking at but not mentioning :-)

Btw: I also changed the header image. If the colours don’t fit at the moment, you probably should clear your browser cache!
