onAfterChangeMonthYear addition to datepicker

onAfterChangeMonthYear addition to datepicker

Hello,

I made a change to datepicker that may be useful to others, so I'm forwarding the idea for inclusion in the widget.

The datepicker widget currently supports onChangeMonthYear callback, but... this gets fired before the calendar view is updated.  If the calendar is sitting inside some flexible container that needs programatic resizing (eg. a div inside a Coda slider panel) I can't use this callback to refresh the view.

What I needed was a callback to fire after the calendar has been changed, so I added onAfterChangeMonthYear in the same style.  See attached file for reference.

So far it seems to work like a charm.
