Vadim Zeitlin c2821dcea0 Allow using arbitrary windows as wxDataViewCtrl editors in wxGTK
Previously the editor created by wxDataViewRenderer::CreateEditorCtrl() had to
be a native GTK+ widget implementing GtkCellEditable interface which prevented
using composite windows (e.g. a container for a text control and a button) as
editors.

Create a helper container wrapping them now and implementing GtkCellEditable
now to allow this.
