Update website

I spent some time updating this website.

Theme

I slightly changed the used colors, highlights are now orange.
The root page is now less cluttered, by removing list symbols and also dropping underlines on links there.

Mobile

BuckMartin.de should now be very mobile friendly.

Products

I added the new category products which will display information about programs that can be purchased.

About / Contact

Both the About and Contact page now hold more information.
