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.

+Sane List Extension for Python-Markdown
+=======================================
+
+Modify the behavior of Lists in Python-Markdown t act in a sane manor.
+
+In standard Markdown sytex, the following would constitute a single 
+ordered list. However, with this extension, the output would include 
+two lists, the first an ordered list and the second and unordered list.
+
+    1. ordered
+    2. list
+
+    * unordered
+    * list
