Christian Hergert fb4fbfb2a8 text: add undo support to GtkText
This adds support using the GtkTextHistory helper for undo/redo to the
GtkText widget. It is similar in use to GtkTextView, but with a simplified
interface.

You can disable undo support using the GtkText:enable-undo property. By
default, it is enabled.
