Fix anonymous user matrix permissions and token authentication

[AdrianFarmadin]

• correct entity type for "anonymous" user
• update config.jelly to match "Matrix Authorization Strategy Plugin
  " https://github.com/jenkinsci/matrix-auth-plugin
• fix for permission matching in token authorization. The token authorization in Jenkins is implemented as basic authentication with email as username and token as password. The matrix has to save user emails to match the users correctly. In UI will be no difference as the email is automatically resolved to user name in "checkName" API call.
• group authority should be objectId
