Bump dependency to 5.14

Nothing has really changed, but I just feel like it. If somebody want to run
this on older perls, it should be doable with some minor patching, but I won't
limit myself from using features in Perl 5.14.
out::torrent: add download dir to torrent show
torrent cmd: add set sub command

You can now query and set values using the following syntax:

> torrent set upload_limit

> torrent set upload_limit 100
