Buildbox Agent 0.2 Release

On July 14, 2014, Buildbox released version 0.2 of its Agent, which includes new features such as artifact downloading and build metadata management. The artifact downloading feature allows users to download build artifacts via the command line in a build step, making it easier to ship assets or binaries from one build step to another. Build metadata can be set and retrieved using the new tool, buildbox-data. Additionally, improved process killing ensures that rogue processes are effectively terminated during build cancellations. The logging system has also been upgraded to logrus for better debugging information.
