Title: Issue # 687 - Calendar remians open after date selection when showTimepicker = false

There's an override to the _selectDate() method that prevents the calendar from closing after selecting a new date. If the timepicker is not enabled then there's no reason to execute this code, it should instead fire the base _selectDate() method since the jQuery Datepicker is designed to close upon selection.
