A way to opt out of disaster rounds

[sartorius]

As it stands, the solarium has nothing to offer except for a rather annoying survival round that is preceded by prematurely ending an ongoing round for all players. As there is currently no reason to do this other than to get a medal for participants, why not have a gamemode vote pop up following a normal end of the round rather than abruptly stopping the current one and causing a massive outcry of "SOL NERDS" from the unwitting participants?
