Hello.
I've simple suggestion: move OreDictionary entries registration and recipe addition to earlier game stage in Exploration module (this code).
This change allows to other mods to add its own recipes and integrations. It also allows to modify these recipes via CraftTweaker.

With current version of ProjectRed (4.8.6.62-64) most other mods can't recognize mod's blocks, because ones are registered too late.

Addressed with f3cbfa5

It should actually be moved to preInit, directly after registration of blocks, if my memory is correct on the order of registry events.
