	This adds a tab

	andlabs/ui is goofy in the sense that you have to determine
	if the ui.Window already has a tab in it. If it does, then
	you need to add this tab and not run SetChild() on the window
	or instead it replaces the existing tab with the new one

	I work around this by always sending a Toolkit that is a tab
	once there is one. If you send a Window here, it will replace
	any existing tabs rather than adding a new one
