Because sometime (when your save and download path are on different drives, when your disk drive is super busy, ...) move operations can stack up, I add this "Moving" status filter so you can see in a blink of the eye which torrents are in a move state.

(Actually it should close all issues about lack of ability to stop torrent after metadata downloaded or after files are initially checked.)
Also makes explicit the temporary start of the torrent in the case when recheck of the stopped torrent is performed.
Sometimes tracker may respond with 0 for num_complete and num_incomplete and we should display that instead of deducing the peer count from peer list. We should only fallback to peer list if tracker does not respond with any information. In such cases num_incomplete and num_complete is set to -1 by libtorrent.
PR #17432.
Change "Incomplete/temp folder" term with "download folder".
Allow to set "download folder" per torrent (in manual mode) and per category (in automatic mode).
Define "torrent ID" concept, which is either a SHA1 hash for torrents of version 1,
or a SHA256 hash (truncated to SHA1 hash length) for torrents of version 2.
Add support for native libtorrent2 info hashes.
Originally, it was just a wrapper for libtorrent::torrent_handle class, so it mimicked its name.
It was then transformed into a more complex aggregate, but the name was retained (just by inertia).
Unlike libtorrent::torrent_handle class in whose name "handle" means the pattern used,
it does not matter for qBittorrent classes and just eats up space in the source code.
