Ex Nihilo

FIX:

• Entirely reworked Barrels behind the scenes. I've done as much testing as I can to ensure this is as stable as possible, but again I ask for some patience on this.
• Reworked Hammer Registry to be less terrible and hopefully crash a little less.

ADDED:

• Ability to obtain Packed Ice: Hammer a piece of regular ice to get Ice Shards. These can be crafted to get the regular ice back, and also packed ice.
• Ability to obtain Double Flowers: Put one-high flowers in a barrel of witchwater to get the corresponding double flower.
• Brand new NEI Plugin! (This is mainly because I accidentally broke the one from NEI Addons)

CHANGED:

• AE2 SkyStone block recipe is now a piece of SkyStone dust in a barrel of lava.
