Title: Transmission torrent-add RPC doesn't accept download_dir as an argument

It appears that the transmission RPC api is rather picky about what it accepts as arguments. I don't know if there it is necessary to have a mapping of arguments to fields or if this will just work.

This at least fixes my problem.
