Allow renaming of the torrent contents/payload

[slrslr]

Hello, qbittorrent and utorrent are having important feature. It allows user to click torrent and on FIles tab rename the files and folders to match his/her existing directory structure. This renaming can be also done right when adding new torrent.

When the file or folder is renamed in the client, then the client will move/rename the files/folders on the HDD.

If i rename files/or folders on HDD, but not in the client, the client should turn the torrent into erroneous state saying it lost access to files.

Things to note:

• two torrents can have common payload files, i rename first torrent payload file/folders and then i rename payload files of the second torrent to match, but maybe the second torrent has incompelte payload downloaded so upon payload rename, the client should not overwrite complete destination files by incomplete ones.
• Windows may have 260 or something limit on path length

If this is time consuming or too complex we could also get option to simply rename elements on torrent list. qBittorrent has something like that. It does not touch files on disc but allows the list to be bit more tidy. Some torrent names can be way too long, and make torrent list unreadable with all the [tags].

Both suggestions sounds reasonable 😄
