0 = Disable palette shifting when submerged or poweruped.
1 = Enable palette shifting when submerged or poweruped.

Enables/Disables the color adjustments when the client picks up a powerup, or the flash when the client picks up an item.
Tints view while underwater, hurt, etc

NOTE: because of the way gl_polyblend is implemented, the client will suffer from a significant fillrate hit whenever the colors have been shifted.
