GAMEPLAY
- Optimization: placed some hints + added portals + dealt with fade distances + some nodraw textures
- Changed orientation of gas particles in back alley
- Modified back alley boiler clip, a dark tunnel one and added new ones for tilted toolboxes (wheels hampered movement)

VISUAL
- Modified some specular textures and volumetric light
- Fixed radar not showing underground passage properly (yellow line)
- Raised a little bit ambient light to facilitate readability. Those who would like to get the older look can decrease brightness a little bit.

Not alpha nor beta, this map is now in released. Have fun!
