* gtk/gtkframe.c: gtk_*_get_arg() and gtk_*_set_arg() implementations.
* gtk/gtkobject.c: new arg `GtkObject::object_signal' similar to
`GtkObject::signal'. check for class type in gtk_object_{setv|getv}.
* gtk/gtkobject.c:
* gtk/gtksignal.c:
* gtk/gtktypeutils.h:
* gtk/gtktypeutils.c: added GTK_TYPE_DOUBLE.
* gtk/gtkwidget.c: new args `has_focus' and `has_default'.
* gtk/gtkwindow.c: new arg `window_position'.
