enableSOCKSProxy - See websocket traffic in Charles proxy

[neoneye]

Here is a possible solution for #240

Usage

import Starscream

class AppSocket {
	private let url: URL

	private lazy var socket: WebSocket = {
		var request = URLRequest(url: self.url)
		request.timeoutInterval = 5
		let stream = FoundationStream()
		stream.enableSOCKSProxy = true
		let instance = WebSocket(request: request, protocols: ["coldwar_mad"], stream: stream)
		instance.delegate = self
		return instance
	}()

	init(url: URL) {
		self.url = url
	}

	func connect() {
		socket.connect()
	}
}

extension AppSocket: WebSocketDelegate {
	// ...
}
