request: torrent directory filtering to not include subdirectories

[smopucilowski]

In transmission-remote-gui and similar, when filtering on directory listings, the main listing is populated with torrents in that directory only, not inclusive of subdirectories.

It would be nice to have an option or toggle to replicate this behaviour.

(My use case: when torrents complete and I ingest/archive them, I move them to a seperate subdirectory --- with the current behaviour, I don't know what hasn't been ingested yet.)
