    userDetails: Add offline support
    
    We want to be able to use the UserDetails class both when the
    user is offline and online. The offline functionality of the
    UserDetails class will only be visible in the UserPopover
    (which will be added in future patches) as there are no offline
    users displayed in the UserList. That being said, details about
    the user need to be shown inside the UserPopover when the user
    is offline aswell.
