Currently Websocket html client example can only process responses from
Zaqar. It can't handle notifications from Zaqar.
When notification is received by Websocket html client example
(examples/websocket.html), javascript console throws an Exception:
TypeError: data.request is undefined
That's because Websocket html client example always expects received
payload('data' object) to have 'request', 'headers' and 'body'
properties. All these properties exist in payload only when response
from Zaqar is received.
But when notification is received, 'data' object do not have 'request'
and 'headers' properties.
This patch makes Websocket html client example able to process
notifications from Zaqar by examining 'data' object's properties and,
if notification is detected, processing 'data' differently.
