Forum upgrade

I upgraded miniBB to the latest version. I tried to do that without breaking any enhancements that were installed. It didn't work for the Poll system, but that's not such a big issue, for the Poll system was bad anyway ;-). As for the other features I don't know wether it succeded so if you find any bugs, please post them in this topic.

As for the recent spam attacks there is a solution – although a drastical one: dissalow unregistered posting and enable e-mail confirmation when registering. During the lifetime of the forums there weren't many unregistered posters, and those that were didn't stay long/advance the community for too long (with the eception of Derek Yu – but he registered now). So I don't know how uncomfortable it will be to force people to register – please state your opinion.

Note also that if it would be implemented this system would stop spam COMPLETELY.
