lookingGlass: Use uiGroup as parent instead of panelBox

Currently lookingGlass relies on some odd BoxLayout behavior, which
allows children to use fixed positioning without affecting the parent's
size request. As this behavior is scheduled for removal, add the
looking glass dialog directly to Main.uiGroup.
