Heads up: new Ethnographer role, content managers and site admins can no longer see and add annotations

OpenEthnographer introduces a long delay in loading pages (only for users with the relevant privileges). While we wait for a more permanent solution, we have adopted a workaround. Its implications are that users with content manager and site admin privileges can no longer see or create OE annotations, and can not see the OE sidebar.

@Amelia, @Inga_Popovaite have been assigned Ethnographer privileges. @danohu has been assigned Ethnographer Admin Privileges.

See this issue on GitHub for a more detailed explanation.
