* Allow organizer to add other organizers to event registration by specifying their username
** The text should read: "Add the usernames of other organizers to give them permission to manage this event."
* Allow organizer to remove organizer
** There should be an area for the organizer to add in the usernames
* If a new organizer is added to an event, they have all basic organizer privileges, including being able to:
** Edit event registration information
** Cancel the registration of a participant
** Open or close event registration
** Delete event registration
* Note that all organizers will have the same rights for V1, but they will have the option to have different rights in V2 (see T316138).
