Ancient Skies

This update represents about a month of community feedback on the balance and design of the pack. We're pushing it out along with a server reset, so please don't  try to update if you're playing on the same world. 

A few things that are different:

- exchanged Traverse for Biomes o' Plenty

- removed Minecraft Comes Alive

- re-added Ancient Warfare 

- removed Dungeon Mobs because the mods weren't spawning very often

- exchanged Agricraft for Mystical Agriculture 

- added Forestry and Cooking for Blockheads

- Removed Roots 

- Exchanged Pewter for PlusTiC and  added Tinker's Tool Leveling

- Removed our cave overhauls, which should contribute to early game balance

- Exchanged Tomb Many  Graves for Lootable Bodies
