Added 'Add Vanilla Override' button when making a 'New Trade Rule'
Added 'View Vanilla Trades' similar to 'View Custom Trades' but specifically for Vanilla Overrides.
Added the following custom settings for Vanilla Trades that can be changed: Minimum Cost, Max Stock, Cooldown, Price Modifier (Price Multiplier), Experience, Per-Player Limit, Restock Timer, Biome (Villagers Only), Weather and Time Of Day.
Official 1.21.5 support.
It's HIGHLY recommended if you have any current Vanilla Overrides in your config to delete them and do them in game through the GUI instead. The syntax/format has changed!
