LinuxTag 2002 is over, but after a LinuxTag is before a LinuxTag.

LinuxTag 2002 is over, but after a LinuxTag is before a LinuxTag.
Hence, we're continuing the development for next year's event.
The current version is exported and should be added to
www.open-events.org soon.  The first set of changes include:

 . Changed style file (changes the db on service.infodrom.org)

 . Changed the title (to make it use the general macro)

 . Use a tag for all days, so the iso date specification is only noted
   in the style file and not in all source files.
