	Allow custom initialization of cell editables.  (#147221)

	* gtk/gtkcellrenderer.h (struct _GtkCellRendererClass):
	* gtk/gtkcellrenderer.c (gtk_cell_renderer_class_init): Add a
	::editing-started signal as a hook for setting up the
	GtkCellEditable.
	(gtk_cell_renderer_start_editing): ...and emit it here.

* @renderer: the object which received the signal

* This signal gets emitted when a cell starts to be edited.
* The indended use of this signal is to do special setup
* on @editable, e.g. adding a #GtkEntryCompletion or setting
* up additional columns in a #GtkComboBox.
*
* Note that GTK+ doesn't guarantee that cell renderers will
* continue to use the same kind of widget for editing in future
* releases, therefore you should check the type of @editable
* before doing any specific setup, as in the following example:
*
* <informalexample><programlisting>
* static void
* text_editing_started (GtkCellRenderer *cell,
* GtkCellEditable *editable,
* const gchar *path,
* gpointer data)
