Drop event not supported?

[wloescher]

It appears that the FullCalendar "drop" event (and the "droppable" and "dropAccept" properties) have not been implemented. If not, I'd be happy to work with somebody on getting these working.

To clarify: I need to drag an element (which is tied to an event) ONTO the calendar and drop it to set the start date, or drag and event OFF the calendar to set start date to NULL.

I also need this functionality to be implemented in ui-calendar.
