Add emojis to chat, upgrade command structure and clean up code

[nullnet0]

Added some cool features and emotes

• Commands and tab completions are now automatically registered by Cloud framework
• Changed AsyncPlayerChatEvent to AsyncChatEvent
• Added Lombok

Emojis in chat:
:downvote: "↓"
:shrug: "¯_(ツ)_/¯"
:tableflip: "(╯°□°）╯︵ ┻━┻"
:upvote: "↑"
:angry: "ಠ_ಠ"

Thanks for the PR, looks like really good improvements! When I test though, it seems I can't run any HCCore commands, is there something more I need to setup?

Getting the error

org.bukkit.plugin.InvalidPluginException: java.lang.NoClassDefFoundError: org/incendo/cloud/CommandManager

now when the plugin is loaded on server start

I tried running the plugin on clear Paper 1.21.1 server with only ProtocolLib, UltimateAdvancementAPI, HCCore and didn't get any error like this. I checked all of the commands and they worked fine.
