WebSocket in relay plugin
Websocket has been added in relay plugin, for IRC and WeeChat protocols.
It is an experimental and partial implementation of RFC 6455: fragmentation and control frames are not yet supported.
The relay plugin automatically detects WebSocket handshake and if everything is OK (origin allowed and required headers received), an answer to handshake is sent and then socket is ready to send/receive WebSocket frames.
Text and binary data are supported, so IRC (text/text) and WeeChat (text/binary) protocols are supported.
