v0.1.3

• Implements the authentication flow with a remote identity provider. The oauth_grant_remote module extends the behavior for the Authorization Code Grant of the simple_oauth module. The identity provider runs an authentication relay, which responds to requests during the authorization flow. The communication utilizes the JWT standard for encoding and decoding.
• Introduces the blocker_mode module, which restricts access to the platform for non-administrative users.
• Introduces new endpoint oauth/expire to invalidate refresh tokens. At the moment is it used to communicate logout actions from the identity provider.
• Activates oauth/userinfo endpoint by overwriting the implementation of the simple_oauth module.
• The workshop course is always locked.
• Updates configuration for REST endpoints to accept request from users authenticated with OAuth.
