[Feature Request] "Tracker Status" Column

[mr.lite.touch]

Request to add a "tracker status" column in the UI.

Torrents on private trackers will often become unregistered. To see the tracker error status of "unregistered", I have to select the torrent, and open the details tab on each torrent. I can have a mix of error statues on a big list of torrents, so I have to manually verify the status of each torrent before I take action. It would be convenient if there were a column to display the tracker status for all torrents, rather than having to check each one individually.
