    Fix bug 9790: Lua: wslua allows duplicate field registration
    
    As discussed in bug 3513 and 9709, one can register more than one new ProtoFields for
    the same field name. Of course C-code can do that too, and does a LOT apparently, but
    if they're not similar ftypes then things can get scrweed up in display filters.
    
    So this change prevents duplicate field registration of dissimilar ftypes. The
    similarity is based on the discussion on the mailing list, and the listing in
    README.developer has been updated to refelect that as well.
    
    Also, this change adds a testscript for Proto/ProtoFields.
