Show number of active transfers in dock

Cyberduck should be able to show the number of active downloads in the doch, similar to the way in which Mail shows the number of new emails. Even better would be if the dock could somehow display the fraction of bytes that were downloaded already, at least if there's only one active download.

As of 61eff28 this must be explicitly enabled using defaults write ch.sudo.cyberduck queue.dock.badge true.
