Update 542: Weekly map update

Version 542 includes our new maps for this week, as well as some fixes for some maps rolled out last week. A few of the maps introduced last week were taken out of rotation due to bugs, but should now be back in rotation with these fixes.

Additionally, there are a few retroactive changes that will affect both new and old maps:

• The post FX volume for killhouse has changed, which changes the overall color temperature of that level. This will also affect training.
  
• CStore storefront shutters now have both blue and red strips to try to help new players correctly identify them as requiring a charge, this helps signal that they normally require a charge to enter.
  
• Added Open and Close SFX for the Vault Door.
