Incremental PTR Update

PTR 4.2.2 update (Build 107138)

• Fix editor crash on right-click.

• A fix to reduce frequency of camera scroll getting stuck. We have a repro and may be able to squash this one for good!

• Fix concealment grasses not appearing when placed in the IGE.

• Normalized announcer sound levels by reducing their volume slightly. Stormgate announcement volume was very loud, and was brought in line with other announcement levels.

• Changed announcer game sound ducking behavior. Previously, when a stormgate announcement played, all other game volume was reduced by 50% during this time. Normal announcements (base is under attack) previously did not duck sounds. Now, all announcements will reduce game sound volume by 25% for a brief moment. This helps us keep announcement volume lower, without being so obnoxious, but still audible even if there's a lot of action. Please provide feedback if you think this goes too far making announcements quieter!

• Removed the ~30% ambient sound and music volume ducking when a unit plays its On Move VO. Units are frequently playing VO so this felt awkward and is unnecessary.

• Lowered fog levels from weather lighting presets, particularly snow.

• Increased brightness at night for all TOD lighting setups to help readability.
