Much updates to map and code

Connected PIS to grid, added Unathi breacher chassis to engineering,
added tables to zap mode, made SM entrence 3x3, fixed BCH room to have
proper atmos and doors, fixed that the electrical crate from cargobay is
now in a locked secure crate only openable by engineers and possible may
have fixed issues with mech bay chargers. Decreased the chance of
insualted gloves spawning in the electrical toolbox, made the
supermatter less prone to exploding right away.
