manually cvs checkin notification

[Jan-Henrik Haukeland]

- made handle_event() in event.c thread-safe
- Deletion of the monit pid file is done as the last thing before exit()
  to ensure that no other monit daemon can start before the current is
  absolutely finnished. There existed a small window. 
- Added a "not monitored" text for services not monitored, instead of there
  status, in the monit web interface. (This has been nagging me a while :)
- Updated the Change log with the changes
