Change earliest shuttle call time to 20 instead of 10.

I remember the good ol' days of barricading myself in the bridge to fight off people trying to recall the shuttle. Then making a hasty retreat through a planed hidden door or a disposal pipe you took apart to escape through the chute.
And yeah the objective was good to prolong rounds. I hated it when people call the shuttle for a meteor shower. The aftermath is the most fun of the round.
