Americanize Contests System (#814)

# Description

I have updated the Contests System to make it safe to use by Americans.
This is accomplished by adding very helpful warning labels, as well as
restricting the Range of all its functions so that they cannot return
either a negative number, or a zero. Therefore, all Contests are now
perfectly safe to divide by.

# Changelog

:cl:
- tweak: ContestsSystem(Mass Contest, Stamina Contest, Health Contest,
Mind Contest, Mood Contest, and Every Contest) have all been updated to
be safe to divide by, since it is no longer possible for them to ever
return 0. Instead they will just return
0.0000000000000000000000000000000000000000000001401298, so if you divide
by an unclamped contest, I hope you like your function randomly
returning the 32bit integer limit.
- add: Warning labels have been added to all Contests to make them
comply with the demands of the American consumer market.
