[pygtk] Undo/redo for gtk.TextBuffer

[Alexander Kuleshov]

Hi to all.

As is well known in gtk / pygtk is no native support in the widget
functionality gtk.TextBuffer Undo / Redo for the text. Collecting the
different techniques, tips, sketches code and using your code appeared
project pygtk_undo which currently provides support for a simple undo
/ redo for gtk.TextBuffer. The code certainly not perfect but I'm
working on its revision. I know that often need this functionality so
I'm telling you here about it, use and modify can come in handy.
