[RFR] Add ability to customize CSV export format

[fzaninotto]

Customize the CSV export format (quotes, delimiter, newline). The default options object is { quotes: false, delimiter: ",", newline: "\r\n" }.

    listView.exportOptions({
        quotes: true,
        delimiter: ';'
    });

Great addon. Could there also be a way to customize the csv filename, for instance to add a timestamp and not just the scope.entity.name() ?

Good idea for an enhancement.
