Added markdown parsing for comments so links in comments now appear properly.

Also rewrote part of the HTML rewriting code so it doesn't introduce an additional wrapping element in the output which was added due to a html5lib requirements on input.

+HTML Tidy Extension for Python-Markdown
+=======================================
+
+Runs [HTML Tidy][] on the output of Python-Markdown using the [uTidylib][] 
+Python wrapper. Both libtidy and uTidylib must be installed on your system.
+
+Note than any Tidy [options][] can be passed in as extension configs. So, 
+for example, to output HTML rather than XHTML, set ``output_xhtml=0``. To
+indent the output, set ``indent=auto`` and to have Tidy wrap the output in 
+``<html>`` and ``<body>`` tags, set ``show_body_only=0``.
