[gtk+] Allow inspection of construct-only object properties

commit af9d59aaca9331f9c31ae4fec518a522602f6176

    Allow inspection of construct-only object properties
    
    The 'Properties' button here is not really modifying the property
    in any way, so it doesn't make sense to disable it just because
    the object can only be set at construction.
    
    This lets us poke at e.g. the cell area of an icon view.
