Identify Mobile and Express client participants

Users can attend a Cornerstone Classroom event from clients other than the App client, such as Express client and Mobile client. The Attendees panel in the App displays such users using different visual indicators so they are easily distinguished from the App users.

For Express client users, the Attendees panel in the App displays the name of such participants in an italicized font. If a leader or co-presenter right clicks an Express client user in the Attendees panel, then the menu displays a title bar with the words "Express client". This allows the leader or co-presenter to know that they cannot promote the user to a co-presenter because the user is using the Express client.
