  From: Simon Glass <sjg@chromium.org>

At present only highlightable objects can be clicked on, i.e. menus and
textlines. Update scene_find_obj_within() so that it can find any type
of object, if requested. Update all the callers to false, so things work
the same.

Since the scene is drawn by iterating through the list of objects, when
the user clicks somewhere we should look at the top-most object under
the mouse first. So reverse the direction of the object search.

Update the tests to cover this new feature.
