GitHub limits API calls to 60 requests per hour from anonymous sources by IP. This explains the intermittent GitHub API failures on Travis.

To solve this, we need to create an OAuth token for GitHub without any special permissions as part of the init automation task and store it as an environment variable in Travis.
