Restore Old Event Rates (#509)

# Description
This restores the basic/survival event rates to how they were before
before #486 (however, it keeps the CVars created in it).

- 5-25 minutes for basic instead of 15-35
- 4-12 minutes for survival instead of 20-45

---

# Why
The PR made it so that survival rounds actually have less events than
extended - that is considering that survival rounds are supposed to be
troublesome and filled with events while extended ones are supposed to
be a chill alternative.

Other forks don't bother with editing CVars every 5 minutes, so this
"opportunity to configure their experience" was never addressed. Based
on the feedback I've received from other players, the change was rather
negative.

From my personal experience, survival rounds became an extended
extended, where during a 2-hour shift you can get a grand total of one
power outage and two mice infestations, and nothing else at all.

# Changelog

:cl:
- tweak: Events should now occur as frequently as before. Note: server
owner can configure the frequency on their server manually.
