Kore message framework example

Run:
```
	# kodev run
```

Test:
```
	Perform a simple GET request against the root page.
	This should trigger the example app to send a message
	to the other workers which will display it.

	# curl -k https://127.0.0.1:8888
```
Add our messaging framework. With this framework apps can now send messages between worker processes. A new API function exists: int kore_msg_register(u_int8_t id, void (cb)(const void , u_int32_t); This API call allows your app to register a new message callback for a given ID. You can then send messages on this ID to other workers using: void kore_msg_send(u_int8_t id, void data, u_int32_t length); This framework will interally be used for a few things such as allowing websocket data to broadcasted between all workers, adding unified caching and hopefully eventually moving the access log to this as well. Some internals have changed with this commit: worker_clients has been called connections. * the parent now initializes the net, and event subsystems. * kore_worker_websocket_broadcast() is dead. 2015-06-22 21:13:32 +02:00			`Kore message framework example`
