echo example

Echo example does the following:

• in a supporter to supporter chat, it repeats everything you say to it, leaves when you leave
• in a customer to supporter chat, when a supporter answers the chat, it automatically joins it and repeats everything the client says, as a comment (client said: ...), stays in the chat until the customer leaves
