Forgotten Nature: duplicate marble, overlaps with Chisel (but there's no config option to disable Forgotten Nature's marble?)

[satoshinm]

Both Forgotten Nature and Chisel world generate marble - found in https://github.com/satoshinm/modpack/issues/53#issuecomment-310871392

Maybe this can't be disabled? http://www.minecraftforum.net/forums/mapping-and-modding/minecraft-mods/1286390-forgotten-nature-1-7-19-a-natural-addition-to-mc?comment=21 says

I realize marble is a common mod addition, so I could add an option in the .cfg file to disable marble.

but this was from 2012, and I see no relevant option in config/ForgottenNature.cfg. Bamboo, biomes, bushes, crafting, crops, trees, as for blocks only:

    B:"Blocks: Camouflage"=true
    B:"Blocks: Crystal Mushrooms"=true
    B:"Blocks: Fig Fruit"=true
    B:"Blocks: New Ores"=false

There's actually at least three marbles:

• Forgotten Nature marble, 3808:4
• Chisel marble, raw marble, 1721
• ProjectRed exploration marble, 3968

Rename the incompatible marbles, and offer recipes to convert? (Minetweaker) Since the Forgotten Nature marble texture is slightly more rough, Rough Marble?
