Script.cs

/* 
    Space Engineers ship emergency stop script by drNovikov.
    v0.51
    
    Saves your ships if you accidentally get out of your cockpit or if you get disconnected from a server. 
    Does not rely on sensors.

    How to use: have a looping timer run a programmable block with this script and also restart itself 
    every second. You can also run the script with the word "manual" as an argument if you want to stop 
    your ship by a quick key, button panel, sensor, timer, etc. 
    
    Additionally, you can place a timer, name it "TriggerOnShipControlLost", and use this timer to set 
    your own actions that need to be performed when ship control is lost.
    
    Special note: scripts need at least one working cockpit, control station or remote control on a ship 
    in order to enable inertia dampeners. It's a good idea to have a remote control block or another 
    control station hidden away from your main cockpit in case the main one gets destroyed mid-flight. 
    If there are several blocks named "TriggerOnShipControlLost", the script will attempt to trigger 
    only the first one.

    What does it do: as soon as the script detects there is no one in control of the ship or any of its 
    turrets, it enables inertia dampeners, turns on gyroscopes and thrusters, cancels their overrides. 
    Also, turns off gravity generators and artificial masses to prevent them from counteracting 
    the inertia dampener.

    Thanks to Mustardman24 for the idea of enabling inertia dampeners by sensors and his script that 
    I initially used for my ships in conjunction with sensors, and later wrote my own smaller version with 
    a reliable way of detecting loss of control.
