Retrieve Participant List, Send Message to Channel and Real JID looku…

…p of participants proxy JID Adds sending message to channel and server forwarding message to participants and reflecting back message to originator. Adds JID lookup request by client and corresponding response by MIX Mock Server. Adds requesting participant list by client and response from mock server.
