There is now a new icon for no requests and another when there are requests.
IMPORTANT: To view the new icon, please update my resource pack. The simplest method is to remove the old resource pack and upload the latest version.
Updated ItemsAdder configs
Updated the ItemsAdder resource pack to use the desired ItemsAdder folder structure for more compatibility.

Added Portugiese Language
Fixed a bug where Player Heads wouldn't load if offline mode is false
Fixed a bug where the plugin was not working with velocity 3.3
