RU TL by Low poly cat

Needed to add a game property to account for loading saved games.

Fixes involved: Changed code to only spawn ruins once all players have founded at least one city, changed the approach to boosting result bonuses in normal huts, and added a large gold reward to the ruin in the event that there are no relic slots.

Narrowed the scope of the slot fix select statement.

Changed to Game.GetRandNum() for PBC support.

Unexplored Ruins will no longer spawn on the same tile as a unit.

Fix for SS. Game modes suck.
