Core/AHBot: Adjust AHBot bid and buyout chances

Apply an exponential formula to define the chance to bid/buyout an auction depending on auction price and item price ratio. The formula can be adjusted changing the new AuctionHouseBot.Buyer.ChanceFactor config parameter
Chance = 100 ^ (1 + (1 - (auction_price / item_price) / k)
k is the config parameter AuctionHouseBot.Buyer.ChanceFactor, the higher the number the higher chance to buy overpriced auctions.
