protected function OfficeHoursDefaultWidget::formMultipleElements in Office Hours 8

Special handling to create form elements for multiple values.

Removed the added generic features for multiple fields:

• Number of widgets;
• AHAH 'add more' button;
• Table display and drag-n-drop value reordering.

N.B. This is never called with Annotation: multiple_values = "FALSE".
