- Remove unnecessary ratio= attributes used with the image shortcode
- Make it so the gloss shortcode doesn't depend on the location of the glossary
within the content tree.
- Make it so the image shortcode understands languages. It will now look in the current
language's content tree, and then callback to the English tree if not found.
- Leverage the above to simplify the Chinese content and remove many absolute references from the
Chinese content to the English content.
