GtkBox should emit signal on adding childs
GtkContainer emits "add" signal, which might be handled. GtkBox is as itself a GtkContainer, but suggested way to add childs to them is through pack_start()
, but looks like this method doesn't emit this "add" signal.
I propose to emit signal "add" when pack_start() is called on GtkBox, to unify handling "add child" event. Thus we can handle "add" method irrelevant how childs were added.
Note: the same for "remove" signal.
