1. Importing the `_content_macros.html` file as a whole, then using the `youtube` macro with a qualified name, so that `bin/compile.py` doesn't have to refer to `youtube` specifically.
2. Concomitant changes in files that directly reference the `youtube` macro.
3. Related changes will be pushed to the `4_0` repo's `blog_excerpt` branch.
