YChatManager

• Fixed config 'enabled' toggles not working for anti flood, caps and swear

They are FALSE by default, but plugin didn't check that and anti-features were always ON. So now you may need to enable them yourself in the config.

• Added Folia support
• Changed player join and quit listeners priority from HIGH to HIGHEST
• Implemented YDevLib to have my common code in one place
• Added bStats
