Final version.
Minor fixes and tweaks.

Some groups appear to be buggy upon inserting the ship to one's personal world. If the hangar bay airlock lights are not automatically turning on/ off depending on pressure in the hangar bay, set this up yourselves.

What we do is tell one of the air vents of the hangar bay (really doesn't matter which one, but we use the one called "Hangar:" (as this is also the one we tell the LCD to refer to through the script for oxygen/ pressure check) to either turn the groups on/ off. The group is called "Airlock lights" (I think. this might differ from one ship to another, but all groups should make sense)
