Untagged torrents

[bigben2k]

I've been using BitComet for over a year, and just love it.

Throughout all the updates, the "Tag" feature really helped me sort through all my torrents, but it is missing one important ability:

- list untagged torrents

As of 1.22, there is still no way to display a list of torrent that are untagged.

Also, if I change the tag of a torrent, it will always ask me if I want to change the directory, even if the torrent is already in that directory.

Otherwise, Cheers for the excellent work!
