Kore example websocket server

Run:
```
	# kore run
```

Test:
```
	Open a browser that does websockets, surf to https://127.0.0.1:8888
	or whatever configured IP you have in the config.

	Hit the connect button to open a websocket session, open a second
	tab and surf to the same address and hit the connection button there
	as well. This should cause the number of messages sent/recv to keep
	incremementing as each message is broadcast to the other connection.
```
Add websocket support to Kore. Introduces a few new api functions: - kore_websocket_handshake(struct http_request ): Performs the handshake on an HTTP request (coming from page handler) - kore_websocket_send(struct connection , u_int8_t, void , size_t): Sends data to a websocket connection. - kore_websocket_broadcast(struct connection , u_int8_t, void , size_t, int): Broadcast the given websocket op and data to all connected websocket clients on the worker. Note that as of right now the WEBSOCKET_BROADCAST_GLOBAL scope option does not work yet and messages broadcasted will be restricted to workers only. - kore_worker_websocket_broadcast(struct connection , void , void ): Backend function used by kore_websocket_broadcast(). Could prove useful for developers to have access to. A simple example is given under examples/websocket. Known issues: Kore does not support PING or CONT frames just yet. 2014-11-24 11:01:12 +01:00			`Kore example websocket server`
