IPN 1.7.1 for fabric 1.15[.1-2]

What's new

fixed fabric 1.16.x build to support Java 8.
Most boolean settings can now be assigned hot key to toggle them in game. GUI settings require reopen of the current GUI.
Config files created by versions prior 1.1.9 are no longer fully supported. If you are upgrading from v 1.1.8 or lower please first install v1.7.0 start the game once to upgrade the config and then upgrade to 1.7.1
Locked slots enable/disable now has effect in single player too.
Fixed modpack arena generation.
Auto refill now takes NBT and Custom Names into account. For all the fake items on servers :)
Added blacklist for items going in the inventory. By default, "carryon" mod is blacklisted.
The configuration file created by v 1.7.1 is not backward compatible.

Switched to modern Kotlin support. This means that this mod now requires Kotlin for Forge or Fabric Language Kotlin
