Reduced the smoke on the minigun and casings for better performance.
Corrected the number of chunks (was 6, should be 8) fired by the flak cannon.
Reduced flak chunk spread (should be ~5.5 degrees, was double of that) on the weapon and slugs.
Reduced the size of the shock rifle combo shockwave mesh to be closer to vanilla UT.
Misc. tweaks to health item textures.
Reduced the blur in the Redeemer view shader, it was too strong.
Fix expiration messages on powerups appearing on level changes.
Address complaints about how I change Kinsie's test map. Shouldn't be too dark now.
Switch ambientglow+brightmap shader to actually use brightmap textures directly. This bumps the version requirement to 3.5.0 and makes it sorta-possible to play with software rendering without seeing "invisible pickup models".
Re-ran all textures through optipng.
All add-ons have been updated accordingly.
