You can do it programmatically by setting the selected date to null, but there 
is currently no way to do it interactively. If editor support were added to 
CalendarButton, you could probably implement something along the lines of what 
you describe.
I did it by showing a button to clear it when it has a value for now. Will provide a patch for editing support later on :)
