Work around Pubnub swallowing errors until https://github.com/pubnub/pubnub-api/pull/179 is merged.

    The Pubnub client library silently swallows errors on sending a message
    (see https://github.com/pubnub/pubnub-api/blob/master/python/3.3/Pubnub.py#L399-L400).
    This works around that problem by copy/pasting the _request() function
    and removing the bare except.

Thank you for providing this option! We are in the process of implement a callback on error with detailed response information. Most atomic calls like publish and history will be simple on error. While subscribe will require something more sophisticated. Thank you for the gist!
