[vtkusers] VTK web application

[Aron Helser]

The older Autobahn had a number of issues with Python 3 - so I would expect
you to have problems. We were able to make it work with python 3 by
backporting a number of python3 fixes, but can you upgrade to VTK 8.1.0?
Then you can use the newest autobahn and twisted, with wslink.

launcher.py has migrated to wslink: https://github.com/
Kitware/wslink/blob/master/python/src/wslink/launcher.py
but it didn't change very much.

I don't know if we have a vtk-only example of migration, but the Visualizer
app migrated, including the launcher, I believe.
