Updated to properly read the node information from nodes with AREDN release 3.18.9. The new release of AREDN changes the formation of the sysinfo.json file and a few updates were needed to successfully read the node channel, bandwidth, etc, from updated nodes.
The Ubuntu 14.04 release will probably work with more recent versions of Ubuntu, but that has not been tested.
The windows version has only been tested with Windows 10.
