commit 31b3f8d8ea31473a7f1e42b642173aed179fab66
Author: Matthew Barnes <mbarnes redhat com>
Date: Fri Jan 18 18:25:56 2013 -0500
EEditorSelection: Keep a weak ref on the EEditorWidget.
Avoids a reference cycle, since EEditorWidget keeps a strong reference
on its EEditorSelection.
This introduces a new function e_editor_selection_ref_editor_widget(),
which returns a new EEditorWidget reference by way of g_weak_ref_get().
EEditorSelection uses this internally and checks for NULL at all points
in case it loses its weak reference.
