The folder that direct downloads temporarily get downloaded to before being moved to the correct location

Removes any "ghost" files in the direct download temporary folder (handy if the application crashed while downloading, leading to half-downloaded files in the folder).

How a torrent that goes seeding should be handled. Either wait until it has completed seeding and then move the files, or copy the files and then delete the original when seeding finishes.

Remove torrents from the download client history when they have completed.
