[!!!][TASK] Improve default csv definition

[Georg Ringer]

use a more realistic export configuration

module.tx_sfeventmgt {
    settings {
        csvExport {
            # cat=module.tx_sfeventmgt/csv; type=string; label=Comma seperated list of fields to include in CSV export (e.g. firstname or event.title)
            fields = event.uid,event.title,event.location.title,event.startdate,event.enddate,event.enableWaitlist,event.enableWaitlistMoveup,uid, main_registration.uid,  confirmed,waitlist,registrationDate,gender, firstname, lastname, title, company, email, address, zip, city, country, notes,registration_fields

this is what a customer wanted and IMO it is a better default configuration because it includes more of what people need and it is easier to learn from that example and adopt it
