VIP Plugins AxBoosters | All-In-One Booster Plugin

- More fixes to make modelengine compatible. (hopefully the last one)
- Attempted to fix an issue with the playerpoints booster

- Some more packet item fixes

Made the plugin not kick players if issues occur with packet items.

- Fixed signs not working
- Fixed villager guis not working.
- Note: ModelEngine is currently incompatible with this version of the plugin. If you are using it, please consider using the last version before the 1.21.5 support or wait a few days until we fix it!

- Added 1.21.5 support. (supported versions: https://docs.artillex-studios.com/supported-versions.html)
- Important: There are some major internal changes to our core api, (AxAPI) so there might be some issues. Please report any unexcepted behaviour at https://github.com/Artillex-Studios/Issues/
- Added a gui-refresh-cooldown-milliseconds setting to the config.yml.

- Fixed vanilla:flight booster not giving fly after changing worlds.

- The plugin now requires java 21 or higher.
- Removed the prevent-booster-stacking setting from the config
- Instead, now there is a new prevent-stacking-boosters section with many settings. Make sure to go through them after updating if you had the old setting enabled!

- The /axboostersadmin apply and unapply now also works from the console as long as a player argument is given

- Fixed an issue with numbers over 2.1 billion being rounded down incorrectly
- Added a metrics system that provides us some basic information (can be disabled in the plugins/AxAPI/metrics.yml file)

- Fixed that boosters with uppercase letters in their name could not be used for permission boosters
