Fix Emc Value of Alchemical Dust

The Emc value in EmcValuesDefault is different than the one in ItemAlchemicalDust. I added the missing value "73728" to ItemAlchemicalDust.

Note: You need to spawn in AlchemicalDust:5 to see it, and the icons are the same of AlchemicalDust:4?

Note: To see the glitch you need to do DefaultEmcValues.getDefaultValueMap().clear()
