Using 'server.console_proxy_disabled' set to 'true' the proxying can be
disabled even if the display ticket is being requested by a different
server than the one that originated the request.
This allows the server to behave the same as before Euwe.
This is an addition to the 2 keys:
'server.proxy_port.start', defaults to 6000
'server.proxy_port.end', defaults to 7000
that allow setting of the port range for the console proxy.
