* Fresh credentials.yml.enc * Update .ruby-gemset * Made PostDeploymentManager modular We broke PostDeploymentManager out into several files to make it easier to maintain. We also added a "force" mode that forces the script to consider all CSV files. This is useful for testing the post-deploy script itself. This should only be used in test mode or you will dirty your database. We also fine tuned some of the logging to make sure that both verbose and non-verbose modes are helpful.
