+	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
