NoFrills 0.4.0 for Minecraft 1.21.5

• This release includes a full rework of the GUI and config system. Some features may not work correctly, as the rework is not fully finished yet.
• The old and unusable config screen has been replaced with a brand new ClickGUI, made with the help of owo-lib (which is embedded in the mod's JAR file).
• The internal config system has been entirely redone, your old configs won't be touched by this version as they are not compatible.
• Includes various improvements, such as an updated Etherwarp Overlay to match the recent changes.
• The YetAnotherConfigLib dependency is no more.
