This commit provides the javascript complement to [WebSocket-Resources](https://github.com/WhisperSystems/WebSocket-Resources), allowing us to use a bi-directional request-response framework over websockets. See websocket-resources.js and websocket-resources_test.js for usage details. Along the way I also factored the websocket keepalive and reconnect logic into its own file/wrapper object.
