Updated the snakeyaml version in build.properties to match what ivy retrieves.
Updated the snakeyaml version in build.properties to match what ivy retrieves.

The snakeyaml file listed in build.properties for the property 'yaml.jar'
was 'snakeyaml-1.6.jar'. However, ivy retrieves 'snakeyaml-1.12.jar' as a
dependency. The version mismatch was causing the build to fail.
