	Settings file
	
	We shouldn't really need settings as this info
	should be stored by app_server, but especially
	BWindowScreen programs cannot now about extra
	features/settings, so we need to store the flags
	internally (until I have a better idea ;)
	
	Especially "SwapWindow" should be mode-independant
	(you don't swap monitors when you select another
	workspace, do you?)
