Fixed plugin use "items" as saved item directory instead of "item".
If your item directory folder is "items" fow now, please consider rename your folder to "item" before update to this version otherwise your saved item data will lost!
Fixed plugin pring item save message in console instead of print to command sender.
Added new item price 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 used. You can consider it as: fuzzy matching.
Fixed item price does not work issue since 3.0.0.
Renamed use-uuid-save-data option to data-save-mode.
Renamed use-left-times-feature option to simply-mode.
Removed double hook item check. Becuase our NBT check method has been used for months and no one said it has problems, so now we remove the second hook item check way and only use NBT check method for now. This will also improve plugin performance in some case.
