[Suggestion] Jet Suits - No Fly Zones

[LemonyGoodness]

I was thinking it would be a good idea if there was a way to paint areas as no-fly zones.  I got the idea for this when I encountered an issue with a vacuum chamber I was using.  Dupes could only get into the chamber if they had a regular atmo suit, but when I had added a jet suit dock to the top of my base...chaos ensued.  The dupes would go to the top to get the jet suit, then go to bottom of the map (where my vacuum chamber is) and fly around in the chamber creating CO2.  This caused a lot of temperature problems since I was handling temperatures in excess of 450C and the vacuum helped avoid heat exchanges.  

If I could have designated the vacuum chamber a no-fly zone, they could still wear the jet suit in the area, just they can't fly with it.  Avoiding unnecessary gas leaks :).
