Updated Skybox, rotated it and added some extra details and fixes, also updated the sky textures to match the maps topside lighting.

More lighting related things, changed around more obsolete entities, and such.

Improved lighting around the map.

More technical improvements and added more areaportals.

Figured out what was wrong with lighting and fixed it, changed a lot of lighting to be done in a consistent fashion and generally a lighting pass.

Fixed a few things i missed and added a easter egg thats very obvious.

Made AMS Cascade logic not depend on lua code that is not available, clipped one last staircase, and added the final nodes to the last room in Xen, basically fully noding the map now.

Most stairs in the map are properly clipped and the nodegraph has been extensively updated, its in rough shape but about 98% of the map has proper noding now unlike the 15% of it before where most werent even connected properly or such, still far from perfect however.

ill finish the rest at a later date, one room in Xen in particular is hard to do properly.

More fixes, more hint brushes being used, Nodegraph has been updated, and Xen Water now uses a newer material meant to better emulate the original style of Xen Water.

Made the map lighting brighter, fixed a bad nodraw in Sector C, converted a few more things into detail brushes, and experimenting with hint brushes to optimize the map further and make compile times less slow.
