Emmanuele Bassi 6e52ef96a4 Move orientable style classes into GtkWidget
It feels slightly wrong to have GtkOrientable operate on widgets, but at
least what happens when an orientable widget changes orientation should
be part of GtkWidget.

This will allow to add more state changes without accessing widget state
from the outside of gtkwidget.c.

/**
* SECTION:gtkseparator
* @Short_description: A separator widget
* @Title: GtkSeparator
*
* GtkSeparator is a horizontal or vertical separator widget, depending on the
* value of the #GtkOrientable:orientation property, used to group the widgets
* within a window. It displays a line with a shadow to make it appear sunken
* into the interface.
*
* # CSS nodes
*
* GtkSeparator has a single CSS node with name separator. The node
* gets one of the .horizontal or .vertical style classes.
