Vintagecraft

- Feature: Added compatiblity for butterfly mania \o/

   (to craft jars use your standard vanilla glass an one lapis, emerald, diamond, lead or lead on top)

- Tweak: Blast furnace now produces steel much more likely

- Tweak: Lignite and Bituminous coal deposits can now also be found up to 40 blocks deeeper than before

- Fix: Might have fixed some odd crashes (occured for me after copying blocks in MCEdit 2)
