v0.5.0 - connect to a socket.io server to handle the messages

• add a socket.io client support on the application

  • mock client - to be able to test the messages flow with the redux

  • socket.io client - to connect with the real socket.ip server (during the development I notice that to make it work on the devices, I needed to define another way to connect to the socket.io server)

• define a socket.io server to handle the chat messages and broadcast them to the others connected users

  • deployed it to the now.sh service, read more about the server on its README.md
