(svn r18726) -Fix [FS#3463]: with non-uniform industries the 'supplies' text when building a station could be incorrect (missing a cargo) -Change [NoAI]: AITile::GetCargoProduction now returns the number of producers and not the number of tiles of producers. -Fix [NoAI]: AITileList_IndustryProducing would omit some tiles for at which a station would get cargo.
