Since Python 3.3 (PEP 393), all Python builds have support for the full range
of Unicode, and hence there are no longer "wide" and "narrow" builds.
Patch by Adam Turner.

Review/refactoring of ``generate_punctuation_chars.py`` including
fixup for r9253: add quote pair for Old Hungarian.

The current algorithm checks each codepoint at least once, and when
``cp_max`` is ``None``, it checks all used characters twice. This
combines the two loops and stores the results of the call to
``unicodedata``.

Also remove the text about "wide" builds of Python, since PEP 393
and Python 3.3, all builds of Python carry support for the full
Unicode space.

Unicode version 7.0 introduced U+2E42, "DOUBLE LOW-REVERSED-9 QUOTATION
MARK", in the Ps category. This codepoint doesn't have a pair
corresponding to it in the Pe category, breaking the assumptions in 
the ``openers`` and ``closers`` strings. The only usages I have been
able to identify are in Old Hungarian, where the character does not
seem to have been used as a quotation mark, so the concept of an
opening character and corresponding closing character do not easily
fit. As the simplest fix to allow tests to pass following
regeneration of the ``punctuation_chars`` file without manual editing,
we remove the U+2E42 character from the Ps category.

Update/harmonize the formatting/layout in both, the generated file
and the generating script.

Remaining differences between the current module and a re-generation result
are due to different versions of Python's `unicodedata` module.

This changes the templates to match changes made to
``punctuation_chars``, making updating the file easier. It also
changes the string wrapping algorithm, leaving less space blank on
each line.

The quicktest tool has not been substantively modified since 2006.
It may still be useful for generating test-cases, so move it to the
developer tools section and do not advertise it as a front-end tool.
Update documentation where relevant to remove mention of quicktest
as a front-end tool, and remove obsolete "EasyDialogs" code path.

Fix typo.
Remove spurious whitespace.
Bare "except" replaced with ``except Exception``.

Specify intended incoding, when possible.

Avoids `EncodingWarning` in PEP 597 and nasty surprises
if the default encoding is not what the user expects.

Keep encoding unspecified where this may be an API change.
