Better history management for plugins

See #2609 (closed)

In a nutshell:

sub init {
    my ($self) = @_;

    $self->addSessionDataToRemember({
        # This field will be hidden from the user
        _language => '__hidden__',

        # This field will be displayed on the portal. The column name
        # can be internationalized
        authenticationLevel => "Human friendly column name",
    });
    return 1;
}
