Flashlights Cigs/lighters Solars RCDs can no longer build airlocks on doors Airlocks now smash glass that is under them when they close AI sat firewall that is not really quite a firewall removed The solars will no longer update if they lack a controler Cut down on machines that don't actually do anything like fake sleepers and shuttle engines There is still a few shuttle engines around and I have no idea where, my map was already corrupted once by this so I am just leaving the define in for now. After a talk with some of the head coders Cyborgs can no longer be traitors at round start Some of the off Z1 areas cleaned up git-svn-id: http://tgstation13.googlecode.com/svn/trunk@2028 316c924e-a436-60f5-8080-3fe189b3f50e
