commit 83ca28cbf95aa95ae5dd93e41a23deb71bb19c7c
Author: anonym <anonym@xxxxxxxxxx>
Date:   Thu Jul 16 22:51:08 2015 +0200

    Allow specifying the Chutney listen address.
    
    It's controlled via the CHUTNEY_LISTEN_ADDRESS environment variable
    (default: localhost). Setting it to some interface's IP address
    allows us to make the simulated Tor network available on the network.
