/*
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
