v0.9.8-r14

rTorrent 0.9.8, -jc Release 14

- Add "download.{active,inactive}" events
  and "d.timestamp.last_active":

  The function is fully event-based, and has a
  well-defined and stable behavior.

  "Activity" here means "last time any peer was
  connected", consistent with @pyroscope's
  definition of "d.timestamp.last_active" in
  https://rtorrent-docs.readthedocs.io.

  Some caveats: the date would only be recorded
  when the last peer disconnects naturally. So if
  the user manually stopped the torrent, or stop
  the rTorrent when the torrent is still active,
  the timestamp would not be recorded. This is
  because when the torrent closes (or download
  object destructs), pending events are destroyed
  as well. Additionally, users have to check if
  the torrent is currently active by themselves,
  so rTorrent does not have to frequently write
  current time to the session.
