AxCalendar | Advent Calendar Plugin v2.8.0

- More fixes to make modelengine compatible. (hopefully the last one)

- Fixed a bunch of reported issues (and fixed modelengine support)

Report any issues @ https://github.com/Artillex-Studios/Issues/!

• 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!

This version of the plugin still might have issues as there are major internal changes, please report any issues @ https://github.com/Artillex-Studios/Issues/!

• 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 1.21.4 support
• Fixed some issues with commands on 1.21+ versions

- Placeholders are now parsed in the gui title when the menu is opened

• Recoded the plugin
• Because the entire reward/gui system was changed, there is no converter, you will have to reconfigure some files!
• The config.yml and the database is unchanged, you can keep that, however the messages.yml was split: lang.yml, menu.yml, rewards.yml
• Added item rewards, so now you can run commands and give items at the same time.
• Simplified configuration, no need to configure 200+ gui config lines anymore, just create a few items and assign a day, slot and reward to them.
• Added 1.21.3 support, so the plugin now works on 1.18-1.21.3 versions
• Improved the 'month' setting, the %time% placeholder will now work with it better

- Added 1.21.1 compatibility
