Fix for endgame crash

[spiritplumber]

Sometimes if you overfill a location with food (for example New Village at the endgame) you get a null pointer.

This is a temporary fix in Location.cs to fix that. It's an ugly fix but it will let you finish/win the game :)

    public Item FindFood(out IItemCollection owner)
    {
        Item item = null;
        owner = null;

        for (int i = 0; i < Rooms.Count; i++)
        {
            for (int j = 0; j < Rooms[i].Items.Count; j++)
            {
                if (Rooms[i].Items[j].FoodValue != 0)
                {
                    try
                    {
                        if (item == null || item.FoodValue < Rooms[i].Items[j].FoodValue || item.Type == Production.Produce)
                        {
                            item = Rooms[i].Items[j];
                            owner = Rooms[i].Items;
                        }
                    }
                    catch (Exception)
                    {
                      // log this to get more clarity, but just adding this lets me finish the game
                    }
                }
            }
        }

        return item;
    }
