Update some gamemodes for co-op support

(these games were made to also be played in co-op, during 1.6 Eric forgot to add the ability to register games in Campaign. Those a mod was required to play such gamemodes in co-op. But thanks to now added Campaign support, there's no more need of such a mod.)
