I continued improving the vis server. The most obvious enhancement are the
calculated ETX values. It is not absolutely correct but sufficient. ;-)
I updated the screenshots on our website: https://www.open-mesh.net/batman/vis
You may wonder why some links are colored (blue, yellow or red) and some are
just grey. The colors represent the link quality of the connection which is
based on the sending and receiving average. Naturally the vis server needs
the packet count of both sides to calculate it. If it is available the links
are colored if not they are just grey.
