allow draft76 websockets (Safari)...

allow draft76 websockets (Safari) Safari still uses draft76, and Tornado 2.2.0 release disables the access from the draft version by default for security reasons. This simply sets the tornado flag to True, so we can continue to support Safari until it upgrades to the RFC 6455 implementation.
