Added -b suffix in action. -b means when multiple products are about to be sold, adding this suffix means that only the first product will be sold and this action will be executed.
Added new sell mode: ItemFormat, instead of require item must 100% equal than selled item, if 2 item's Item Format is same, we will also consider the item can be selled. You can consider it as: fuzzy matching.
Added new command: /shop generateitemformat, will parse hold item into UltimateShop's ItemFormat, if you don't know how to write Item Format, this will very useful for you.
Fixed /shop saveitem command does not working well since 2.1.0.
