As noticed in issue #2458, intercom sounds did not stop when pausing the game or loading a mission. I fixed this by augmenting `main_hall_stop_ambient()` to also stop the intercom. Additionally, it turns out that the intercom delays were not being calculated correctly due to a very bizarre random number formula. I overloaded `rand32()` to add a min/max variant and used this instead.
