Hacking at 0300

I've had some questions about extending flexcal so I created one that combines filtering, output formatting and drop-down menus.

The filtering will only allow dates going back 17 years, and the calendar will start on that date. The formatting will use European dates (d/m/y). The drop-down menus will be the ones from the original post, but instead of using aspect-oriented programming (flexcal('after', '_adjustHTML', function (cal){...) we will subclass the original widget.
