Parsing deploy config fails unless struct tags are modified

[sqs]

If I create a _jekyll_s3.yml file as described, parseDeployConfig returns a DeployConfig struct with all zero values. But if I apply the following patch, it reads the values into the struct correctly.

diff --git a/config.go b/config.go

Are you using an old version of launchpad.net/goyaml, perhaps? (I just made sure I am on the latest version of goyaml.)
