New feature
You can run `yarfox search <pattern>` to display toots matching the given pattern.
Breaking change
The layout of the files stored on disk has changed to be more sensible.
JSON files used to be named `<tail>/<head>.json` where `tail` was the last 2 digits of the
toot ID, and head the reminder of the ID. (Don't ask ...)
Now they are named `<year>/<month>/<id>.json` which hopefully makes more sense.
Any way if you were running yarfox version 1.0.x you should run `rm -fr ~/.local/share/yarfox/` before re-running `yarfox fetch`.
