Change the location where the Worker writes its local files so that it
follows the XDG specification (instead of writing to the current working
directory).
- Linux: `$HOME/.local/share/flamenco`
- Windows: `C:\Users\UserName\AppData\Local\Flamenco`
- macOS: `$HOME/Library/Application Support/Flamenco`
NOTE: The old files will not be loaded any more. This means that if
nothing is done and the new worker is run as-is, it will reregister as a
brand new worker. Move `flamenco-worker-credentials.yaml` and
`flamenco-worker.sqlite` to the new location to avoid this.
Building this site requires Hugo (not yet included in the README or in the
installation of dependencies in the Makefile). Still very much work in
progress, this is basically the [Geekdocks theme][1] + one page.
