Plugin TrackLabels

Description

The plugin adds a set of labels on the category panel. These labels are created automatically on the basis of torrents' trackers.

Some non-obvious points

• Labels are created for all trackers of zero-group of the torrent. So some torrent may be present in several categories at once.
• The method of creating a tracker's name has been "borrowed" from Deluge. It is heuristic and cannot guarantee always correct result. For example if there are two trackers in the zero-group: http://clients-tracker.depthstrike.com and http://core-tracker.depthstrike.com, the label depthstrike.com will be created and the torrent will be counted twice in it.
