Added Custom Trade Cooldowns, by default there will be no cooldown (0) and if you already have custom trades you should be unaffected. You can always add a cooldown whenever you'd like in the Custom Trades viewer GUI (/trademanager)
Adjusted the GUI text slightly so that it's a tad bit more user friendly. I'll be actively doing my best so that it's simple to understand in the future! Visit the discord for any help as per usual.
Trade cooldowns were already possible for Vanilla Trades through the Vanilla-Overrides configuration file, however it wasn't possible for custom trades but now it is!
