Thinking of it a bit more: let's just disable automatic switching to the next level, after finishing the current.

This was the kde3's katomic behaviour - manual level switch.

Also this resolves the problem with saving _solved_ game.

Although, I admit that some players might like this automatic switching to the next level...
Well if they exist, let's wait until they complain :-).
And then I think I can add some config option to satisfy both kinds of players.

Heh, I'm quite mouthy today :-)
