[MAP] Brig Cleanup

-Fixed several broken atmos pipes
-Fixed AI blind spots (Execution chamber excluded)
-Removed armory-equipment room airlock. Less holes in the armory, the better, what with the new brig control-sec office airlock
-Fixed the button change in brig control being reverted
-Removed sec office light switch from under the airlock for real this time
-Removed airlock from execution chamber access
-Changed execution chamber access. It requires Armory access to enter, but HoS access to use.
-Removed Labor shuttle - prison wing connection as it defeated the purpose of having it by the warden's office with blast door controls
-Expanded the evidence room and added a real airlock to it
-Moved several vents that were hidden under objects
-Fixed brig control grilles not being shocked. Again.
-Other stuff I may have overlooked when writing this changelog
