    st-theme: ref items in custom stylesheets list
    
    st-theme stores some loaded stylesheets in a custom
    stylesheets list.  When removing items from this list
    it unrefs them, but when adding items to the list it
    neglects to ref them.  This means that under certain
    circumstances the list will contain items that have
    already been freed.
