Modified chat script a lot. Main improvements are to the general order of the conversations. I find myself more and more storing variables in the HTML elements themselves and I think it would be best to transfer all functions and variables into the table cells with the class conversation_cell. Also decreased the pull rate to help ease network traffic. The next step would be to have a single request to get all new messages but the problem with this is sending multiple latest_pulled and latest_seen values with the single request. Not impossible though.
