New design of web page

The web page of the Mathematics Information Service hat got a new design and appears now in a fresher outfit. At the same time the web page moved and is available from now on under the address fidmath.de. A forwarding from the old address vifamath.de is also established. In the course of this modernization the single pages are revised and their content is adapted to the Mathematics Information Service as follow-up project of the Virtual Library of Mathematics vifamath.
