Has it changed?

Grabs current version of each page in a list, and checks against previous stored version. Sends email and stores new version if there is any change. Currently uses sendgrid to send the email. Configuration is done through environment variables. Example environments are in the examples directory. These environments can be instantiated using envdir.
