Test case

When i use gtk_menu_attach_to_widget (attached testcase) i get the following warnings:

$ valac --pkg=gtk+-3.0 src/test.vala
/vcs/gnome/gnome-contacts/src/test.vala.c: In function ‘_test_menu_detach_gtk_menu_detach_func’:
/vcs/gnome/gnome-contacts/src/test.vala.c:53:2: warning: passing argument 1 of ‘test_menu_detach’ from incompatible pointer type [enabled by default]
/vcs/gnome/gnome-contacts/src/test.vala.c:46:13: note: expected ‘struct Test *’ but argument is of type ‘struct GtkWidget *’

The problem is that the callback type gets a widget, but the callback is on a widget subclass, so the pointer type is wrong and needs a downcast.
