Switch to Hugo 0.47 (#2288)

- Fixes the bug where not all of our files would get the right lastmod
time extracted from GitHub.

- Fixes most of the cases of bad HTML output around the use of {{<text>}}. There's
still a single bad case which I'll report to the Hugo folks.

- Use Hugo's new --minify option to minify HTML instead of having to use the
separate and slow html-minifier program.

- Fix some bad HTML on the landing page.
