v0.2.0 (Go rewrite)

This release is a complete rewrite of chef-runner in Go -- a real programming language that makes it easier to maintain and extend the code base.

The rewrite includes the following changes:

• chef-runner no longer uses Vagrant's Chef configuration. Instead, it creates
  its own local .chef-runner folder where configuration data and cookbooks are
  stored. This is the first step towards supporting systems other than Vagrant.
• chef-runner no longer supports long option names like --host and
  --json-attributes. All original short options are still supported though.
• rsync now only copies actual cookbook files and is run in verbose mode by
  default.
• Events are now properly logged to the console (in color!). The log level can
  be controlled via the CHEF_RUNNER_LOG environment variable.
• There are new scripts for bootstrapping, building, and testing the project in
  script/.

Hope you enjoy the rewrite. More features to come soon!
