Fixed an issue where disabling "Display Disabled Trades" setting would remove similar Custom Trades.
Disabled Trade checks will now exclude Custom Trades (as it was always intended).
Minor/rare issue with Per-Player Max Uses was also fixed (Thanks to @toyotaz for testing that led me to stumbling on this).
This basically means you can disable a trade like emeralds and still have a custom trade that gives emeralds (Thanks to
@dshimenfor bringing this issue up on discord!)
