Fewer Mid-Round Events (#486)

# Description

Ports and improves
Simple-Station/Parkstation-Friendly-Chainsaw#59

Slows rounds down so the station doesn't always have to evacuate in a
blaze and can instead leave complete.
Also makes Survival not stupidly destructive and gives a chance for the
shift to last a decent time.
Allows servers to configure the times themselves if they want to, so
defaults don't matter too much.

# Changelog

:cl:
- tweak: Mid-round events will occur much less often
