Editabledatefield - datepicker is not appearing in safari

[robbyahn]

While looking at options to change date format to NZ, showcalendar is from browser not from SS framework when I create date field in userform.

In Safara (Mac), datepicker is not showing up.

@robbyahn jQuery datepicker is no longer supported with SS 4, see: https://docs.silverstripe.org/en/4/changelogs/4.0.0/

I'd check out this module as recommended in the thread referenced: https://github.com/praxisnetau/silverware-datepicker
