message structure

{
    messageType: <string>,
    message: { id: <number>, text: <string>, sender: <string>, sent: <datetime>, link: <url>, channel: <number>},
    command: { id: <number>, command: <string>, params: [<string>: <string>]}
    data: <json structure>
}

Based on MessageType the client/server should know what to react with

eg - if messageType === 'message'
then Display sender/sent/text on screen
if messageType = 'image'
then display image from url on screen - optionally add text if supplied

Commands
/join - join channel - params: name: <channel name>
/

data should always be accompanied with either a command or a message details
