Title: Add {Connection: Upgrade} field to upgrade reply header. and change "Sec-Websocket-Origin" -> "Sec-WebSocket-Origin" in reply header.

Weberknecht (websocket client for java) can't handshake to cowboy. Because weberknecht check "Connection" field in reply header,.
And can't handshake, when reply contains "Sec-Websocket-Origin" in header. But handshake is completed when reply header contains "Sec-WebSocket-Origin".
