Optional on delete confirmation dialog

[fatzopilot]

I would be great to have an optional dialogue that asks for confirmation if the user is going to remove some records.
An easy way would be to add a simple option, e.g.

ListGrid.setCanRemoveRecords(true);
ListGrid.setConfirmRemoveRecords(true);
//optionally, set dialogue title and message 
ListGrid.setConfirmRemoveDialogue(String title, String message);

A more fine grained way would be to provide a handler that determines, whether a record should really be deleted. The developer then could add some additional information into the dialogue or do some other actions.

ListGrid.setDataRemoveHandler(new dataRemoveHandler{
   onRemove(Records[] records){
      //create message text
      String message = createDeletionConfirmMessage(records);
      SC.say("Confirm deletion", message, new BooleanCallback() {	
			@Override
			public void execute(Boolean value) {
				return value;
			}
		});
)

Would also be great if a dataRemovedHandler, i.e.

ListGrid.setDataRemovedHandler(DataRemovedHandler handler)

was added at the same time.
