v0.23.0

• Support for django-style database settings as the first argument to the
  Chancy constructor to ease integration with Django projects.
• Chancy's dashboard and API now require a login by default. If the CLI is
  used to start the dashboard without an API configured, a random temporary
  password will be generated. Authentication backends are pluggable, and Chancy
  comes with an optional DjangoAuthBackend.
• The dashboard's live event stream is temporarily removed due to Websocket
  routes not properly supporting authentication.
• Many documentation tweaks
