Chat.js updates

We need the following updates to our chat.js;

• instead of using appendP for 'CHAT' 'REGISTER', call the new display-text-message function to append a new message, passing it the params (username and message)
• Register a different handler for app 'CHAT' and method 'REGISTER', the handler should be called 'updateUsers'.
• Also register a handler for app 'CHAT' and method 'DISCONNECT', also calling the same 'updateUsers' handler (perhaps build this function and add it to the helper directory)
• This function will be called with two arguments, 'sender' and 'users'
• (sender will be 'server')
• (users will be an array of objects, in the following form; [{username: 'john', permissions: ['av', 'chat']}...])...
• Inside this function, for each user object, check whether the user has chat and av permissions.
• If they do have both permissions, and there are no \
• elements inside of the \
  element (I.e no Mentors), append a new \
  • element to this \
    , with the username as the text, and a class of 'online__user'
    • else if they do have both permissions, but there is already a \
    • element in the mentor
      , add a \
      • to the moderator \
        • else if they only have chat permissions, add a \
        • element to the student \
          .

is the online__user class should be added also to the moderator and students? @njsfield
