Refactor shell scripts.
- Avoid relative paths, so I can run them from any working directory.
- Make a dedicated curl-wrapping shell script instead of re-defining the
  same alias everywhere.
- Support extended offline periods: allow get-webmentions.sh to fall
  back to the cached copy of my webmentions for up to a day, and don't
  accidentally destroy it; keep changes atomic.
- Verify that the fetched webmentions are legit before replacing the
  cached ones.
- Make shellcheck happy about quoting in vnu.sh by passing the list of
  files with xargs instead of a shell variable.
