New plugin for dumping .torrent info

[TheGoblinHero]

Regularly I need to export info about torrent (all filenames, exact size in bytes, etc) to the text format. So I wrote a simple plugin: The plugin uses external tool to dump the torrent. Personally I use old dumptorrent utility with several patches, but it's configurable, so you can use any utility you want.
