Guests are allowed to post again

[TiKu]

Some months ago spammers forced me to deactivate the Guest account. During the last days many spam accounts were created, so I implemented a mod so that you have to enter a displayed code on registration now. I hope the spam accounts were created by bots, otherwise the new visual code confirmation would be useless.

While searching for the mod, I found another mod which inserts the same visual code confirmation if you try to post without being logged in. So I implemented this mod and reenabled the Guest account.
