Suit GPS, Helmet Control, and Door Control with Anti-Theft

Caution: Anti-theft system in place. If this suit ever lacks a helmet, such as if the suit is unequipped on player death, the chip enters a 'death state' where it no longer functions. If a player attempts to equip and use the suit after this, not only will it not work, it will close and lock the helmet, while setting pressure and temperature to lethal levels. Even if the IC is moved to another suit or re-exported, it will continue to not function; you will either need to get a new chip, or reset the deathstate var yourself in the code. A suit with its pressure and temperatures set to kill mode will be basically impossible to get back to functioning levels, even once the chip is removed, without clicking (literally) one million times to lower the pressure. If you wish to re-use a hardsuit that has been stolen, you must insert a working version of the chip which will reset the values to appropriate levels Provides automatic helmet control, closing your helmet in unsurviveable conditions, and opening it while turning off suit filters when in good atmosphere. Also acts as GPS toward 0,0,0, where most bases are located at the default spawn. Then whenever you move, your suit pressure is adjusted subtly based on whether you're going toward or away from the base. If lost, try going in a circle until you see the pressure above 50, then continue that way, trying to get the pressure to show as high a value as possible (shouldn't go much more than +/-10 unless you go really ham with your jetpack to go super fast)​ Can be used to control custom made IC door systems; set up an IC housing that the user is expected to drag this chip to, with d0 pointing to the IC controlling the door system. Change securityCode var to be any number you think other people can't guess. When inserted into a housing with d0 connected, chip will set the Setting on d0 to its code, which you can verify on the other IC and open the door or whatever. Note that if d0 is not set on this housing, the death sta
