[Request] Make custom dimensions load earlier

[MCTian-mi]

I'm trying to cleanup GregTech CEu's ore vein display page for JEI, where I added some display items as ingredient for the ore info wrapper

However, I've noticed that due to AR dims are registered during server starting (FMLServerStartedEvent), which is much later even compared to JEI finalizing, the custom dimension display items won't get added properly.

This is easy to solve, tho. By moving the dimension registration earlier (like, to FMLPreInitializationEvent), this can be solved easily without significant downside effects to the mod.
