module_chat_list_parse.js

/* This module is responsible to go through the list of chats (with unique users) and find out
   the chats with an unread message. It should then open the unread chats on by one, after which
   the message reply module will start its work.

   DONE:
   -> Read through the message list
   -> Open all the chats with unread messages

   PENDING:
   (Not done as is useless to do unless we can actually reply to a message)
   -> Integrate with message reply module
   -> Cycle through the chat list
   -> Poll for new messages, once the current list has no unread messages
   -> IGNORE group chats
