Reduce the amount of one-shot shell scripting during development

It would be nice to be able to use symlinks and hugo's ability to reload dynamic files during development, rather than needing to re-run localbuild.sh.

This produces three benefits:

• The golang is probably more approachable for many developers, especially as the find commands become more complex.
• The golang templates are applied when the content is rendered, which reduces the risk of corrupting static files, since they won't be rendered through the template.
• When complete, it should be possible to use a static docker image with the website and map the "docs" directory into it for live iteration using the actual website rendering.
