Torrent client updates

Two quick notes about recent torrent client developments:

- qBittorrent Enhanced (https://github.com/c0re100/qBittorre...v4_4_x/NOTE.md) is currently not allowed on DigitalCoreClub. This may change in the future if and when we have a chance to vet it, but it isn't on the whitelist of approved clients.

- qBittorrent v4.4.x - many users are using the latest version of qBt successfully but please make sure that your not trying to force Bittorrent v2 mode. This shouldn't be an issue for most people as the DCC tracker doesn't support v2 and this should all be automatic but the staff has already had to expend resources assisting users experimenting with it at DCC. It ain't gonna work, so please don't waste your time or ours.
