added creating engine snapshots when using mouse click events

Before, when using mouse click events as CE change events, clicking on
a CE with mouse click event did not save a new game engine snapshot,
so undo/redo of CE mouse click events did not work.

With this change, undo/redo snapshots will also be created when using
mouse click events.
