Calling socket.stop() causes an AttributeError

[oughtotrade]

When I call stop() on the listener socket I get the following AttributeError.

<snip>
  File "/home/anon/.virtualenvs/anon/local/lib/python2.7/site-packages/betfairlightweight/streaming/betfairstream.py", line 56, in stop
    if self._socket is not None and not self._socket._closed:
AttributeError: 'SSLSocket' object has no attribute '_closed'

I can't find this _closed attribute in any of the Python documentation or else I'd try and file a PR for you!

Thanks, _closed is a protected member which I assume py2.7 doesn't have, will just remove so that the shutdown is attempted regardless.

Just reviewed the source code for socket and _socket, it looks as though shutdown actually calls close() so this can be cleaned up as well.

Thanks, good result. I'd patched it locally in the same way you modified it and it was working fine (for py2.7 anyway).
