New layout.

Finished updating the layout of the site, and tweaking some things like the documentation. Manuals can be added to a game page now and can be added either as as a .zip file, or multiple files can be selected at once and the server will zip them up into a single file. That said, the manual for "Die Höhlenwelt Saga: Der Leuchtende Kristall" can be downloaded from its page now, which includes a translation of the manual and lore book that came in the original box.
