drag 'n' drop reordering

[André.Bisseret]

Bonjour Éric,
Excellent :-)) I haven't noticed yet this grab command ! I just tried  
it ; very simple ; with mouseMove as well as with mouseDown.
I kept  "if shiftKey is down" . And, in order to avoid the actions  
launched by mouseUp, I put "if the shiftKey is down then exit mouseUp",  
in the mouseUp handler.

Best regards from Grenoble
André
