Subject: [PATCH] SimpleChatTCRV:CMOptimisedShow: User respones

Now even the user response handling flow (handle_user_submit) has
been updated to use the optimised chat show logic which adjusts
/ updates the chat session ui wrt the last two messages only and
not the full chat history in the chat session.

Move the logic wrt last two messages and ui, into its own func
and inturn use it everywhere as required.
