This cleans up the global namespace by explicitly exporting shared values. All html and JavaScript files have been converted to use explicit exports except for client.js and mocha-init.js
When using qbittorrent-nox it is not always possible to manually create
the target path for torrent moving. This commit allows automatic path
creation. It also allows to display error messages in the
'Set location' window.
The feature is useful when the user needs to move their torrent to a
sub or parent folder. If more than one torrent is chosen, the path
of the first selected torrent is used. The window was made wider to
allow more convenient editing of long paths.
