Added new wool item
Added wool selling to stables vendor, works with the same auction system as selling livestock but uses a different selection of rewards (WIP)
Has the same three strike system - three different rewards are offered one at a time, if you reject all three the vendor won't accept wool for 15 minutes
Rewards are based on amount of wool out of 1000, so you are incentivised to bring more in a single visit
Wool stacks to 100
Fixed a bug in ItemContainer.UseAmount that prevented it from deducting multiple stacks
