Now throttling ShopUtility to once every 3 seconds (except when we have stash access).
Fixed a bug where shopping would stop after buying an item that is out of stock.
Removed useless code from ShopExecute since ShopUtility is now throttled.
Fixed bug with CourierCare not being able to upgrade the courier.
PreGameUtility value is now 99 and no longer configurable.
Disabled pregame behavior overriding.
