JER Not showing blocks from modded Dimensions in World Gen tabs. Also not showing blocks that I KNOW generate in the overworld, Like DeepSlate diamond/DS emeralds/DS gold/DS redstone ores. World-Gen.json is in config folder, but its like it only sees part of it.

Mods have to add their own support to show their ores in the World Gen tab. User workaround used to the profiling but that remains to be re-implemented.

Added deepslate stuff in 0f66af1, will be in version 1.1.1.
