Conection frontend to backend

• Using ajax and javascript to send data on every button click or keystroke press.
• Keystrokes(wasd and arrows, space or escape for stop) P.S speed up and down not implemnted yet

Future fix of delay from frontend

Use socket.io and get bi-direcation connection to the server. This way sending data will be very low latency.
