Describe every setting under its name

Properties can carry a one-line description, set with
NamedProperty.description for mods, a ConfigManager.property overload for
the client's config, and a helper in ModLayout. PropertyList rows show it
under the setting's name in muted text. Every mod, HUD layout, general,
UI style and animation setting now has one.
