Almost a year and a month after I said I was working on it, I finally got it done. This update includes:

Additions

• Eco-Handler Rewrite => Support for CoinsEngine, though currently only for one currency
• Updated GUI and UTIL stuff

Bug-Fixes

• Eco-Set Menu now works up to version 1.20.4
  
• some more, forgot which ones though
  
  
• (no idea if the weird chat bug is till around, so yeah...)

Removed

• Had to disable the explicit maraidb support, since for some reason the package added a few mb to the file size which spigot didn't like...
  Currently mysql is fully supported (at least version 8) while mariadb compatabillity might depend on your setup

Known Bugs

• You can still shift click items into the GUI since my fixes haven't worked so far....
  If you want a way around that, refer to the conversation between me and SecretxCipher in the report-a-bug channel on the discord
