    gtkplacesviewrow: plural form for available space
    
    We were not supporting plural form of the available space, which
    is a problem in some languages.
    However in this case is kind of a difficult matter, since we use a
    formatted string from glib with g_format_size.
    
    To fix it, use the same behavior as g_format_size to decide when
    it should be used a plural form or not.
