This document contains detailed description of WebSocket-based protocol used to proxy RCON.
When user connects to the WebSocket server (by default at path /ws/console) he/she needs
to authorized because only users with administrator access rights can get access to the console.
Authorization is pretty straightforward: user sends his/her access token id and if it's a right
administrator access token then server sends back an ok string. After this "handshake" client
can send commands to server and server will send back a result if any. All communications are just a plain text.
