Use Enter and Space for cell editing in generic wxDVC too.

Use Enter and Space for cell editing in generic wxDVC too.

If the normal Enter or Space processing (sending activate event or doing
activatable editing respectively) isn't handled by the control, use
these keys to trigger inline editing too, as F2 does.

This makes the Windows control more similar to OS X and GTK+ ones and
makes discovering editability easier.
