TOF : Disable Dark Mode in 2021r3.1

#1 
private func setDarkMode(darkMode:Bool) {
	if !darkMode {
		NSApp.appearance = NSAppearance(named: .aqua)
	} else {
		NSApp.appearance = NSAppearance(named: .darkAqua)
	}
}

Override SYSTEM level, and set dark/light specific to a given app

Obvious that code is Swift, and needs to call the proper Xojo “declare”
