br_08_bar_ambi_bw10_02.thn: Previously this bar script used the correct starsphere but it didn't have the correct white tint that the Bw10 starsphere has. This has now been added for the bar script.
cv_01_bar_ambi_ew01_01.thn: This bar script used a generic nebula as a background. However, this station is not actually in a nebula. The script has been modified so it uses the Ew01 starsphere background.
Adjusted the ambient lighting for all bar scripts so the space backgrounds look more like Leeds; the colors weren't accurate before. In the br04_02_base script, the stars have also been removed because Leeds doesn't have stars either.
