Fixed plugin using "items" folder as a catalog of saved items instead of "item".
If the items catalog folder is now "items", please rename the folder to "item" before upgrading to this version, otherwise your saved data will be lost!
Fixed plugin displaying a save item message in the console instead of printing it to the command sender.
Added a new item price mode: ItemFormat, instead of requiring that the item must be 100% equal to the item being sold, if two items have the same Item Format, we will also assume that the item is usable. You can consider this as: fuzzy matching.
Fixed an issue with item price not working since version 3.0.0.
Renamed the use-uuid-save-data option to data-save-mode.
Renamed use-left-times-feature option to simply-mode.
As of version 2.7.0, the name parameter is used as the display name in the item format. However, in previous versions, the display option was used as the display name of the item. The plugin will now read both parameters at the same time to avoid situations where the new version fails to recognize the corresponding custom item name after loading the old version's configuration.
