    userPopover: Add user popover
    
    We add the UserPopover because we want to add a more
    convenient way of accessing the information of the
    UserList without actually locating the user inside
    a potentially long list. Moreover, the UserPopover
    will be able to provide details when the user is
    offline as well.
