elm_box: emit child,removed and child,added, allow smart-recalculate of box. 

* proxy signals from evas_object_box: child,removed and child,added. Both
   will carry event_info being the child element.
 * elm_box_recalculate() to force recalculation of internal box, thus
   applying the layout to children.

Thanks btdrucke for reporting!
