ProductBin: a binned product names its maker's line and a floor; the mint draws above that floor

Browse source 
FactionProductData slot 7 Bin (schema id unchanged, additive as slot 6). Mint derives a bin's
distributions from its line on every lot, truncated by NextGaussianAbove (64 tries, then the cutoff).
