Disk space sorter (for lack of a better name)

[Gregorio Litenstein]

I don't really have the required skills to do this but it would be insanely useful and perhaps not too hard.

How about a plugin that takes a numbered list of volumes/drives as its input and, upon automatically opening/saving a torrent, it iterates through the list checking for available space, and then puts it in the first place with enough space. If none of them has the space, usual behavior would trigger.
