[script-torrent-done] variable with tracker needed

[verysofttoiletpaper]

This is a request for the inclusion of a variable containing the tracker domain/hostname/url of the torrent to be passed to the script-torrent-done.

This would allow the torrent-done script to do execute only for some trackers, or to have his behaviour modeled by the tracker.
This would be useful for example to organize torrents by tracker, or to run scripts tools like filebot (http://www.filebot.net/) only for torrents coming from certain trackers.

How to deal with torrents with multiple trackers?
I the case a torrent has multiple trackers, the tracker information would not be relevant, so the variable could be empty (to simplify).
Other sensible options would be, passing just the first tracker, or passing a list of trackers separated by a comma or by some other method.

Thank you
