Update the field with the given dateFieldName with the dateString that has been passed,
and hide the datepicker. If no dateString is passed, just close the datepicker without
changing the field value.

Also, if the page developer has defined a function called datePickerClosed anywhere on
the page or in an imported library, we will attempt to run that function with the updated
field as a parameter. This can be used for such things as date validation, setting default
values for related fields, etc. For example, you might have a function like this to validate
a start date field:

function datePickerClosed(dateField)
{
  var dateObj = getFieldDate(dateField.value);
  var today = new Date();
  today = new Date(today.getFullYear(), today.getMonth(), today.getDate());
