Subject: WINTERMUTE: Add FoxTail saveslot timestamp getter

FoxTail requires Game.GetSaveSlotDescriptionTimestamp for getting
information about saved games.
Engine 1.2.362 and below returns object with Description and Timestamp
fields.
Engine 1.2.527 and above returns array[2] with Description and Timestamp
as items.
