python: post installer docs fix script

* Moved post_installer.py into the examples/howto/ directory.
* Added instructions for its use to the Python Bindings HOWTO.
* Ran it as intended from the lang/python/ directory in order to both
  prove it works and quickly and easily get the updated howto
  replicated.  Also to fix all those .texi files.

+~~~~~~~~~~~~~~~~~

+Following installation it is recommended to move the
+``post_installer.py`` script from the ``lang/python/examples/howto/``
+directory to the ``lang/python/`` directory and run it. This will fix or
+restore files needed by Sphinx which may be removed during a
+distribution build for release. It will also generate reST files from
+Org mode files with Pandoc and generate Texinfo files from Org mode
+files with GNU Emacs and Org mode (in batch mode). Additionally it will
+fix the UTF-8 declaration line in the Texinfo files (Emacs expects
+\"UTF-8\" to be \"utf-8\").
