Fixed in trunk (r8068).

http://svn.mirrorbrain.org/viewvc/mirrorbrain?view=revision&revision=8068

I used http://opensource.depthstrike.com/torrent.php/MPlayer-
1.0rc2.tar.bz2.torrent as (hopefully valid) example.

To configure the nodes, a MirrorBrainDHTNode config directive was added, which 
takes two arguments (hostname and port).

Torrents should contain a nodes key.

Harold: uTorrent uses the nodes key for backup DHT bootstrapping information 
incase other "more primary" information fails

It sould be made configurable with different servers.

There is documentation at http://www.bittorrent.org/beps/bep_0005.html that 
suggests that nodes keys should be added only for trackerless torrents, but Harold 
said that information is outdated since the core change (BitTorrent.com switched 
to the uTorrent core).

Note: remove source code comment in mod_mirrorbrain.c about this.
