Fix some Markdown warnings

Browse source 
Fixes the following warnings when run with Markdown 2.6.11:

DeprecationWarning: "safe_mode" is deprecated in Python-Markdown. Use an HTML sanitizer (like Bleach https://bleach.readthedocs.io/) if you are parsing untrusted markdown text. See the 2.6 release notes for more info
DeprecationWarning: Using short names for Markdown's builtin extensions is deprecated. Use the full path to the extension with Python's dot notation (eg: "markdown.extensions.extra" instead of "extra"). The current behavior will raise an error in version 2.7. See the Release Notes for Python-Markdown version 2.6 for more info.

Also get rid of some compatability code for Markdown 2.0, which we no longer support.
