ubuntu-application template uses GtkVBox instead of GtkBox

[Alexandr]

Hi!
ubuntu-application template uses GtkVBox which is deprecated http://developer.gnome.org/gtk3/3.2/GtkVBox.html and it's confusing. You can't add GtkVBox in glade, only GtkBox and then set it as vertical.

Maybe it should be changed in template GtkVBox to GtkBox + vertical?
