MC Plugin ExtraStorage 3.16.2

Let your players have their own storage to store items when they mined or picked up it, and more...

DATABASE LOGIC CHANGED. MAKE SURE TO TEST BEFORE UPDATING TO PRODUCTION SERVER.

• Migrate the database logic to Topper
  This change is a preparation for an upcoming update adding proper support for cross-server storage.
  For now, the plugin would "lazily" update the database, meaning the database is only updated when there are changes in player storage. This would improve the overall performance (hopefully).
• Use PlayerDB to fetch texture
• Increase the support range for storage spaces

• Add a permission to allow player to send pickup items to their storage
  exstorage.storage.pickup
• Add a patch to clean up all invalid items and empty string in database
• Update UniItem to fix a problem with eco plugins
• Add a permission section in the wiki

With this update, ExtraStorage is now open source.
If you are a developer, you can now access to the source code and make changes and contributions.
If you are a new user and want to test the plugin, you can now access to the source code and build the plugin yourself for free.
However, the support server is only for those who bought the plugin.
There will be more major updates since I'm planning to replace the current codebase to one that uses my library.

• Open source
  https://github.com/HSGamer/ExtraStorage
• Change package name to me.hsgamer.extrastorage
  Those who make integrations should update the plugin
• Support Java 8 and newer
• Cleanup useless things
• Revamp the plugin page

• Withdraw Command should now respect the maximum amount in an item stack
• Clear some unused files

• Add support for Nexo
  Now you can add items from Nexo to the storage
  The format for it is NEXO:<item_id>
  This is untested (because I don't have a copy of Nexo), so take this as a caution, take a backup before updating and please report if you find any issue
