Change the default behavior when regex exclude/file size filters match all files

[Blonks-afk]

I've been looking around through previous issues and discussions and I've seen a couple places where regex filters either didn't work, or they did work but because all of the files in the torrent were matched to the exclude filter, it defaulted to the fallback behavior of downloading all of the files.

To me, this seems counter-intuitive. For most other configuration options, the default behavior is to mark the torrent as failed and move on (such as with the retry download options). Typically a user would be setting the exclude filter because they explicitly do not want some file type.

Whether that is to ignore the increasingly common .lnk malware attempts, to exclude certain media file types that they cannot use, or even just not wanting small files. I feel that the explicit exclusions set by the users should be respected rather than have the default option be the polar opposite of that.

If there is some additional information or situations that lead to it being implemented this way though, I'd love to hear them.
