Newer autobahn python/js are needed to support longpolling.
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
For ParaViewWeb clients with browsers which do not support websockets, autobahn now supports longpoll instead. Version 0.8.14 of autobahn|python and the latest autobahn|js are required to support this feature in ParaViewWeb.
Additionally, small updates to the vtkweb.connect javascript module are needed to support this change.
