Extend option to copy torrent files to a folder

[WillyWolly]

I have a suggestion to make this checkbox work as follows (also currently in qBittorrent):

After checking the option to copy torrent files to a folder, all torrent files that have not yet been copied are copied to the specified folder when the setting is applied. That way I can have a collection of torrent files available even if I didn't check the option at first (since the files in the state folder have unrecognisable names).
