Boolprop is a boolean setting that can be toggled in the game using the
developer console. Many of these consist of usercfg settings that are
not exposed to the Settings UI window, and secret testing functions.
Where one points to usercfg, check usercfg.Settings for documentation
about what that boolean does.
