Subject: [PATCH] urlencode now handles parse_qs encoding correctly.

The autobahn websocket protocol.py line 2487 uses parse_qs(query) which always returns a list as a return value.
For example:
urllib.parse.parse_qs('room=test') returns {'room': ['test']}.
In order to parse it correctly later, doseq for urlencode must be set to True.
