Transformation bug involving metadata

And now in the right branch...

I found a bug that you could only transmute blocks in the world with metadata and most of the time it wouldn't even do it, and I have fixed that. All I did was to go to com.pahimar.ee3.core.helper.TransmutationHelper.transmuteInWorld() and changed the world.setBlockMetadataWithNotify(x, y, z, targetID, targetMeta); to world.setBlock(x, y, z, targetID, targetMeta, 2);. Now it works perfectly. I am sure you have already fixed this, but I wanted to have this on the repo, just for good looks.
