Add option to extract all archives to torrent root, destination folder, or true in-place.
Add sonarr/radarr support (marks torrent "incomplete" until extraction is done).
Bundle 7z.exe for windows users.
Fix GTK UI not working...at all.
Improve web and GTK UI so they're uniform, have radio buttons, etc.
