Adding in the new staircase spawn to match the new areas from the occupation version; moved to my own tab; touched up nodegraph; did a lot of optimization

Fixed some skybox issues; updated member list; added in some HVAC units to the roofs in one area

Fixed a bunch of lingering post-war elements; member list; navmesh

Hopefully improved FPS stopped any assets from not being in the BSP.

Outside concrete ground should not be as shiny anymore.

Fixed more doors and touched up lighting in a bunch of places.

Fixed a soundscape; fixed the issues with the doors throughout the map. Should all work now.

Fixed a issue with a wall in d2_prison_07 as well as a large door that wasn't moving correctly
