Subject: * fixed "nobody " -> "nobody" fuckup when getpwnam-ing * implemented
 basic blacklisting: ** the file specified with -b <BLACKLIST> is read and
 added to a blacklist vector ** if an announce hits a torrent in that
 blacklist vector, add_peer_to_torrent fails ** sending a SIGHUP to the
 program forces it to reread the blacklists ** the server returns with a 500,
 which is not exactly nice but does the job for now ** an adaequat "failure
 reason:" should be delivered... TODO
