add file log page to cm

* Only send and receive logs are shown
* For older version, client send to server doesn't have size information, because server side doesn't know the total_size
* Not switch tabs automatically when new files are transferred
* If cm side page is open, not pop up automatically when new files are transferred
* Show unread message count
* The cm tab remains open when closed if a file transfer has previously occurred
