Breaking changes:
* Some filters, sorters and columns have been renamed for consistency
* The file priority 'shun' is now called 'off'
* The 'details' command has been renamed to 'summary' ('details' still works
as an alias)
* The default keybindings to start/stop torrents have changed from <t+p> and
<t+P> to <t+s> and <t+S> (so we can open the peer list with <t+p>)
* For boolean settings, the values 'enable'/'disable' have been replaced by
'enabled'/'disabled'
* The 'clearlog' command has been removed (see new 'log' command)
* The setting 'tui.cli.history' has been renamed to 'tui.cli.history-file'
* The 'rate' command now accepts the same values for its LIMIT argument as
the settings 'srv.limit.rate.up/down'
Other changes:
* New commands: 'trackerlist', 'tracker add|remove'
* New contexts for keybindings: trackerlist, tracker
* New command 'log' can clear the log, scroll up/down and append info/error
messages to it
* New server settings: srv.utp, srv.dht, srv.pex, srv.lpd, srv.port,
srv.port-forwarding, srv.limit.peers.global, srv.limit.peers.torrent,
srv.autostart-torrents, srv.part-files, srv.encryption
* New setting: tui.cli.history-size
* New setting: remove.max-hits sets the maximum number of torrents that are
deleted without extra user confirmation
* Filters, sorters and columns now have shorthand aliases
* New default keybinding: <t+p> opens a torrent's peer list
* New default keybinding: <t+t> opens a torrent's tracker list
* <ctrl-l> now hides/shows the log and <alt-l> clears it
* <backspace> reverts a partially entered keychain by one character
* <ctrl-c> is now bindable and no longer raises KeyboardInterrupt

* The 'rc' command no longer fails if it encounters a command that is not
supported by the active interface
* Foreground colors in the tab bar are now all bright in the default theme
* Time deltas now show seconds if less than two minutes away
* Use pyxdg module instead of appdirs (if you installed with pip, run
`pip3 uninstall --yes xdg`)
Fixed bugs:
* Long torrent lists in narrow terminals no longer take ages to print
* In torrent details, the 'Completed' date was displayed as the unix epoch
(1970-01-01 ...) if unknown, and the 'Ratio' was displayed as negative
values if unknown/not applicable
* Don't throw 'Unclosed client session' errors when opening multiple
torrent lists at once while not being connected to the daemon
* Don't crash with 'KeyError' exception when opening many torrent lists at
once while being connected to the daemon
* Some columns in torrent, peer and file lists were unnecessarily wide
* Don't crash with BrokenPipeError when piping output to tools like 'head'
