NANCY: Mass detection adds non-games

[tunnelsociety]

I guess some Nancy games could use detection table additions. I might attempt this; meanwhile, ticket to track.

Mass Add on some Nancy discs adds multiple of what is apparently the same version of games--for example, 3x "Nancy...Moon Lake (Windows/English)"--but only one of them works correctly: in all my cases the extra games present the Main Menu without music and then ERROR on New Game.

For example, mass-adding a directory which contains:

• nancy7 DOG disc files may add subdirectory "DataFiles"
• nancy1 SCK disc files may add subdirectory "GAME"

(All appear in the list with the same name; I differentiate via Game Path in Game Options. I wonder if when a game is added which already has the exact same name, we should append something like an ordinal...)
