NQ of a CellMove does not result in an event message

[mkromberg]

Run Demo_Issue296, and enter the following from the session:

      eNQ 'F1.VGRID' 'CellMove' 1 3 1

The server sends the following message:
{"NQ":{"Event":"CellMove","ID":"F1.VGRID","Info":[1,3,1],"NoCallback":0}}

The grid currently moves curcell as requested, but it does not generate an event. It should send something like:

{"Event":{"ID":"F1.VGRID","EventName":"CellMove","EventID":"e6206aff-cc5f-485f-b51e-9176e25b8d31","Info":[1,3,0,0,1,0,""]}}

Note that, although the Grid should NOT generate an event if you click in a cell which is already current, it SHOULD send an event in response to the NQ, even if the NQ specifies the cell which is already selected.
