Set an unique cookie name.
As can be seen in discussions like http://stackoverflow.com/questions/1146112/jsessionid-collision-between-two-servers-on-same-ip-but-different-ports
and http://stackoverflow.com/questions/1612177/are-http-cookies-port-specific, RFC 2965 says
cookies from one port of one host may be sent to a different port of the same host.
This means if someone runs multiple Jenkins on different ports of the same host,
their sessions get mixed up.
To fix the problem, use unique session cookie name.
This change breaks the cluster mode of Winstone, as all nodes in the cluster must share the same session cookie name.
Jenkins doesn't support clustered operation anyway, so we need to do this here, and not in Winstone.
