Subject: [PATCH] add "signals" for start and end of screenshot capturing. Like
 the other signals, this is meant for attaching listeners. The ufo will use
 that to hide/reveal the status line in screenshots. The following signal
 properties are now available:

  /sim/signals/exit       ... set to 1 right before quitting
  /sim/signals/reinit     ... set to 1 on re-init  (Shift-Esc)
  /sim/signals/screenshot ... set to 1 before and to 0 after screenshot
  /sim/signals/click      ... set to 1 after mouse clicks at terrain, signalling
                              that the geo coords in /sim/input/click/ were updated
