Fixed a bunch of bugs with nodraw, fixed some missing doors, fixed light brightness...

Added some more lights, neon signs, and two combine monitors in the plaza area.

Added the eifel tower in the distance, it will remain unlit for a bit!

Lighting fixes + removal of some hidden doors.

Another quick bugfix.

Fixed bad texture seaming, and removed some of our crappy nodraw work :(

First patch! Replaced the Citadel with the basic HL2 one.
