Village Life

This is a big release. Here is an overview:

-Removed Modular Systems as it was causing a crash with NEI when opening a recipe
*Added Extra Utilities and extra for better metallurgy compatibility
*Added Mob Control with a setting to remove Zombie Pigmen . . . they were being auto agro'd in the nether by monster swarm and that seemed too "hard core"  for a mod pack that isn't given that label. Disable this for a harder game if you want. :)
*Added in Jabba for early storage. Play testing showed that barrels might be needed prior to warehouses coming online.
*Added in Ars Magica for those looking for a more magical path. This pairs well with Botania in my opinion.
*Configured Special mobs so that ghost spiders wouldn't walk through your walls and kill your villagers despite your best defenses. That just seemed cheap.
*Set a default configuration for open blocks preventing a skeleton death spiral from happening in the nether. It's still pretty brutal there.
