This signal is a sign for the cell renderer to update its
value from the cell_editable.
Implementations of GtkCellEditable are responsible for
emitting this signal when they are done editing, e.g.
gtk.Entry emits this signal when the user presses Enter. Typical things to
do in a handler for ::editing-done are to capture the edited value,
disconnect the cell_editable from signals on the gtk.CellRenderer, etc.
gtk_cell_editable_editing_done() is a convenience method
for emitting editing-done.
