As part of the process of adding support to LT 2.0, we should stop using all deprecated function, as some (if not all) were removed. For this process, we should use the LT 1.2 upgrade (guide)[1]. The change includes: * stop using file entries directly * start using the torrent handle's set/unset flags * stop using url key in add_torrent_params (for magnet) * stop accessing resume_data from save_resume_data_alert * stop using deprecated session status keys in UI [1] https://libtorrent.org/upgrade_to_1.2-ref.html Closes: https://dev.deluge-torrent.org/ticket/3499 Closes: https://github.com/deluge-torrent/deluge/pull/342
