Add Admin view to chat logs

[AmitBerg]

Add option for admin user to view the logs of chat rooms.

• This would be implemented by adding FileView to all the log files in /media/chat/logs (csv files).
• The page would have basic html page that shows the messages between the people.
• The conversation can be read by the read function (in counsmers.py) and passed in the context to the page. If we want the page to show the conversation "live" we should consider using REST (ApiView) to send the data without re-freshing.
  use Jonathan easy_rest live_context, examples in code.
  to change the speed of the retrive:
  window.contextUpdateInterval = 1000
currentPageContextFetcher.bind();
