Set up web socket endpoint for receiving log information

[hitman401]

Set up web socket end point for collecting log information using socket.io
Once the setup is in place, test it by sending a log information from maidsafe-utilities websocket test. The test runs an server by itself, hence comment that part and point it to the express server endpoint.

• Must be able to receive the message from the test
• Should be able to get the secret token from the message received. This will help to validate the source message for the actual implementation.
