We may have to change the extra gold gen in Mesa biomes: MinecraftForge/MinecraftForge#3774

I haven't looked at our code in quite a while so I can't remember it very well, and I'm not sure if there's anything we need to do here.

At most, if we call the vanilla procedures while at the same time manually generating the extra gold and sending a GenerateMinable.EventType.GOLD, we might just have to remove our code that does the ore gen, and let the vanilla procedure do it's thing.

If we don't call the vanilla procedure (manual biome decoration) then our code can probably remain unchanged.

Closing this in favour of rewriting how RTG is generating ores, This issue can be dealt with then and won't be done until 1.12.
