From 2ade53f268df7c34bc334895ab0cc360732a8140 Mon Sep 17 00:00:00 2001

Subject: [PATCH] three --css modes: gmi.css, base and none   when "none"
 inline tags will be wrapped in <p>

--image, --audio and --video now accept the extensions to inline
  so what's possible to load isn't maintained here

--lang is now referred to as --html
  --html and --body are mutually exclusive
