Qbittorrentui

- Add support for modern Python

- Strip Unicode version selectors from torrent names to prevent formatting issues

* Upgrade panwid from 0.3.3 to 0.3.4 for Python 3.10 support

* Fix ETA formatting

- Only attempt to automatically connect to qBittorrent when explicitly configured to do so

- Update to `panwid==0.3.3`, use `blinker-alt==1.5` instead of `blinker==1.4`, and latest version of `qbittorrent-api`
- Fix color scheming for torrent rows so all qBittorrent torrent statuses are supported and colors update in real-time with torrent status
- Stop application crash when a category is added in qBittorrent
- General code cleanup and misc fixes
