So it is here, after a long time, new thing! 🥇

What did I did?

• Reworker Config to use Configurate library as it is amazing as hell! 👍
• Separate Core version and Main version
• Introduced Guice support
• Introduced Player and Plugin wrapper for more easy cross-platform developement
• Preparing for new big things 💯
