UX: Improve torrent status line

The goal of this commit is to merge the two torrent status lines onto a
single, concise line which has high signal and information density.

- Hide download speed, upload speed, and number of peers when 0,
because that's just noise.
- Remove number of files, because that information can be found by
expanding the torrent.

This also allowed the further reduction of the torrent item height from
110px to 100px.
