    Revise lingo enumeration for sample products
    
    Added a new enumerator with the explicit value zero, corresponding to an
    empty string, which is important because zero is the default value for
    database entities. Removed initializers for other enumerators to show
    the effect of such a change: the '.database' and '.lingo' files hold a
    different index, but looking up that index in the lingo map yields the
    same string.
