[Seth Vargo < >]

Ohai Chefs,

I just release Chef Zero v2.0.2 with some critical bug fixes/improvements: https://github.com/opscode/chef-zero/releases/tag/v2.0.2

• Fix a series of typos in the README
• Read JSON, not a file path in from_json
• Fix IPV6 support
• Remove moneta as a dependency

Happy cooking!
