Getting drag and drop to copy (not cut) dragged text

[depstein at att.net]

Thanks very much.  Dave Cragg found the message I was missing: "dragEnd."  

It makes sense that after a "dragDrop" has happened there's a "dragEnd" sent 
back to the dragSource, since MC's default behavior needs to react to the 
user's choice of drag destination, and either leave or delete the dragged 
text in the unlocked source field.  So anything I do to that source field in 
the dragDrop handler will be undone by MC's automatic response to "dragEnd."  
By trapping dragEnd, I can control the fate of the source field.
