[WIP] Necropolis part 2

I'll try and keep this up-to-date with changes to the lower three levels of Necropolis.

z-2, 1st real vault level, architecture is mostly done but connections to z-3 still need to be updated/added as it is built [explorable]
z-3, housing, architecture roughly 25% complete

The barracks area in the top left region is already blocked off so you'll have to teleport in and open the door for yourself until I get z-3 up.
Fancy barricade :P
