[torrent] support recursive folders

[raphamorim]

Today, we support Torrent structure like

- myfile.mp4

First Case

However, we need to understanding formats like (animes/novels/drama torrent formats), e.g:

- myFirstEpisode
- mySecondEpisode
- myThirdEpisode
...

Clapton should understand this structure and create a playlist from it.

Second Case

- myPaste
   - myAnotherPaste
      - myMovie.mp4
