A better calendar widget.

The current calendar widget is very slow. Opening a browser window is outdated for this type of widget.

There is an excellent one called Javascript Advanced Calendar Script over at http://www.garrett.nildram.co.uk/calendar/jacs.htm

Options to mouseover a field, click a field or click an icon. Optional date formatting also.
I'd like to suggest this one be implemented in future builds to replace the current one.
