This also comes with some mechanic changes to icebox labor, given
there's no more shuttle: You still teleport people into the labor camp,
but when the amount of points have been achieved, you can walk through
the point gate rather than needing to fly a shuttle home.

## Why It's Good For The Game

The labor shuttle didn't have much of a reason to exist on icebox, you
weren't flying anywhere, you were just walking a few steps downwards

Integrating it into the perma-brig allows for a more unique labor
experience than other maps, and one that fits the setting a bit more

## Changelog

🆑 Melbert
add: [Icebox] Security saw a minor remapping, with most notably the
removal of the labor shuttle and the integration of the labor camp into
the bottom floor of the perma-brig.
