This is needed to forward declare this type and pass it by value.
Conversion from/to QVariant are hanled via Q_DECLARE_METATYPE, while
TorrentState::toString() function was used in webui only and as such is
moved there.
The function returns list of availability values for all torrent files.
The availability here is different to that one in the progress bar. Here
it shows what part of the file's pieces is available (i.e. we do not count
availability > 1 for a piece).
Arguments include adding torrents as paused/started, skiping hash check, setting category, downloading in sequential order, downloading first and last pieces first, and skipping the 'add new torrent' dialog. Added TriStateBoolOption class for specifying options that don't have a default value when unused (e.g. add-paused). Also improved command line usage text to include more information, have better organization, and not exceed 80 columns in width. Also also added firstLastPiecePriority field to BitTorrent::AddTorrentData, and modified TorrentHandle so that if first/last piece priority should be on, it will be toggled on after the torrent's metadata has loaded.
Fix issue when you rename the "root item" in the "Add New Torrent" dialog
and uncheck "Create subfolder", it will create the subfolder with the
renamed name.
Fix PropertiesWidget first folder is expanded after app restart.
Strip root folder if torrent was added via magnet link.
Fix crash when you get name of torrent without metadata.
