/// Version of the current game data
/// Usage: Always save for the most current version but include loading code that can cope with file format changes
/// If a format change occurred that can still be handled increase this version and handle it in the loading code.
/// If the change is to big to handle increase the version in Savegame.cpp and remove all code referencing GetGameDataVersion.
/// Then reset this number to 0.
/// TODO: Let GO_Type start at 0 again when resetting this
/// Changelog:
/// 2: All player buildings together, variable width size for containers and ship names
/// 3: Landscape and terrain names stored as strings
/// 4: HunterWaitingForAnimalReady introduced as sub-state of HunterFindingShootingpoint
/// 5: Make RoadPathDirection contiguous and use optional for ware in nofBuildingWorker
/// 6: Make TradeDirection contiguous, Serialize only nobUsuals in BuildingRegister::buildings,
///    include water and fish in geologists resourceFound
/// 7: Use helpers::push/popContainer (uses var size)
/// 8: noFlag::Wares converted to static_vector
/// 9: Drop serialization of node BQ
/// 10: troop_limits state introduced to military buildings
/// 11: wineaddon added, three new building types and two new goods
/// 12: leatheraddon added, three new building types and three new goods
/// 13: SeaId & HarborId: World::harborData w/o dummy entry at 0
/// 14: Remove "age" field in nobBaseMilitary
/// 15: Add sea to HarborPos::Neighbor
