Updates box2550Away

- Anchors all computer frames
- Adds survivor Ian (he didn't exist back then but the map is already
full of anachronisms). Adds snack wrappers to HoP office in an attempt
to explain his survival. I think players will like the idea of Ian
outliving the dead old characters on the map.
- Breaks all food and drink machines and adds an Out of Order paper
floating on them suggesting the reader goes back to the station if
they're hungry or thirsty.
- Removes detective's security camera TV because it doesn't work
off-station and there aren't cameras anyway.
- Removes the dead AI and dead slime as both had issues. This fixes #2533.
- Fixes beer keg and cola incorrect object paths.
- Fixes AI module incorrect object paths.
- Removes all but one SWAT body armour from the armoury. Removes two of
the SWAT helmets, leaving two behind.
- Emags the maintenance door to and from the portal so those without
maintenance can enter and exit the portal room.
