    directory: Rename set_directory_rooms to append_directory_rooms
    
    A function in directory.rs is currently called set_directory_rooms, but
    it's used in a way so that it appends rooms to the directory list.
    
    Renaming the function to append_directory_rooms will clarify what it's
    actually doing.
