Dependency

The plugin uses NBT API(item-nbt-api-plugin) to manage plugin items
Before plugin version 1.20, NBT API is integrated into the plugin beforehand
From plugin version 1.20, users have to visit the home page of NBT API to download and install it manually(put it into /plugins folder), so that icbmBukkit can works properly
The aim is to make updating NBT API more easily
