Challenge games should skip the intro
Right now you get the "For 6000 years..." screens when starting a challenge game. Since there's no plot in the challenge games, we should probably skip it altogether.
As in the description.
And since we're here: ADOM might also print the current challenge week when starting the game and also add "Week XX in 2017" or something in the highscore details for that particular challenge game.
