Morale System (Port From White Dream) (#620)

# Description

This Feature has been graciously provided for Einstein Engines to port
from the White Dream codebase.

Mood is a system for tracking a character's current Mental State, which
fluctuates throughout the round as a result of various events that can
modify it. Each consisting of a single line event that can be trivially
inserted into any other system, and a yml configured "Moodlet", which is
applied to said character. Moodlets can be temporary or permanent, and
can also modify a characters mood in either positive or negative
directions. Things like, "Being Hungry", "Being Injured", "Petting a
cute animal", "Being Hugged", all create a Moodlet.

Mood can provide buffs or debuffs, primarily to movement speed. In fact
Mood's movement speed modifier actually completely replaces the movement
speed modifiers from Hunger & Thirst. Instead Hunger & Thirst create a
negative moodlet that persists until you eat and drink, which _can_ give
you a speed penalty. But you might for instance diminish the negative
effects by seeking out other positive sources. Or they might just get
worse, who knows what could happen?

# Media

Mood takes the form of a series of Moodlets, which modify your
character's internal Mood stat. It's kinda like a healthbar, but for
your mental state. Whenever you gain a moodlet, it appears in a popup.
White text for standard moodlets, red text for negative moodlets. By
clicking on your mood icon, text will show up displaying all of your
currently active Moodlets.

# TODO

- [x] Refactor the Crit Threshold modification, and Movement Speed
Modification to make it more granular.

# Changelog

:cl: VMSolidus & Skubman
- add: The Mood System has been ported from White Dream. Mood acts as a
3rd healthbar, alongside Health and Stamina, representing your
character's current mental state. Having either high or low mood can
modify certain physical attributes.
- add: Mood modifies your Critical Threshold. Your critical threshold
can be increased or decreased depending on how high or low your
character's mood is.
- add: Mood modifies your Movement Speed. Characters move faster when
they have an overall high mood, and move slower when they have a lower
mood.
- add: Saturnine and Sanguine have been added to the list of Mental
traits, both providing innate modifiers to a character's Morale.
