copy/paste insertion of trackers gone in 2.92 [well, not quite]

[thimk]

Please, I would very much like it back - it helps me immensely to insert a curated list of UDP-trackers

I can copy the list from an older torrent on the list, but when trying to paste it, nothing happens. I can see in the top OSX menu of Transmission that the paste-option is greyed out.

UPDATE: After restarting 2.91 to see if the problem was the same there (it was not) and then re-starting 2.92, paste is no longer greyed out, but 2.92 crashed upon insertion of copied tracker list - and when re-opened, the list is there, but acquiring the list of active seeds and peers takes a loooooong time.

Actually, it would be a very nice thing to be able to paste only UDP trackers, as http trackers put a great load on servers.
