v0.3.0

The following non-breaking changes have been made in this version:

• Cleaner method to set config using input variables using aws configure instead of ~/.aws/credentials and ~/.aws/config files.
• No longer sets --delete and --follow-symlinks flags by default — this may have been self-centered of me! These can be configured by adding args: --delete --follow-symlinks to your personal workflow file.
• SOURCE_DIR environment variable is no longer required. Defaults to the root of the repository if not set.
