Originally, it was just a wrapper for libtorrent::torrent_handle class, so it mimicked its name.
It was then transformed into a more complex aggregate, but the name was retained (just by inertia).
Unlike libtorrent::torrent_handle class in whose name "handle" means the pattern used,
it does not matter for qBittorrent classes and just eats up space in the source code.
This applies to "About Dialog", "Ban List Options Dialog", "Download From URL Dialog", "IP Subnet
Whitelist Options Dialog", "Search Plugin Select Dialog", "Search Plugin Source Dialog",
"Statistics Dialog", "Speed Limit Dialog" and "Torrent Options Dialog".
Also unifies storing the dialog size under the key "Size".
Now it is defined as:
CacheStatus.readRatio = (blocks read from cache) / (blocks read from disk + blocks read from cache)
The 2 variables in denominator are counted separately and the formula before this change doesn't really make sense
Add percentage sign to "Read cache hits" stats
Also remove redundant header include
Change project directory structure according to application structure.
Change 'nox' configuration option to something more meaningful 'nogui'.
Rename 'Icons' folder to 'icons' (similar to other folders).
Partially add 'nowebui' option support.
Remove QConf project file.
