    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,
    as there are no offline users displayed in the UserList. We
    know which case we are in by the presence of the _user variable,
    which is passed as parameter at construction time. We also update
    the messageButton visibility whenever we set the _user variable,
    as messaging a user is only available in the online case, and only
    when the user is different from self.
