``--`` appears in a comment, which makes the comment not a comment

- deprecate fooBarXyz functions, such as ``educateQuotes`` and
``processEscapes``

``Attr.q | Attr.b | Attr.i | Attr.e``

- ``_str_attr_to_int()`` to handle str-type before the removal

- deprecate function name ``smartyPants``, now ``smartypants``

- remove ``tags_to_skip_regex`` and add ``tags_to_skip`` as a list of
skipped HTML with a helper function to compile a regular expression

* command-line

- add ``--version``
- add ``--skip`` for skipped elements

- ``test_pep8``, ``test_pyflakes``, and ``test_test`` (unittest)
