Tone/map disable switch?

[Major Cooke]

There's a time and a place where auto tone adjustments can be made... and times where they shouldn't be. I'd like a switch where if someone disables it, GZDoom's current tone/exposure settings are turned off and reset to the default values. Meaning any darkening/brightening of the scene is undone and set back to normal.

And while we're at it, can we please get a menu for this stuff? I still don't see why we don't have a specific place for the exposure settings, but at the very least include something so I don't have to suffer darkening issues while playing a baron of hell in D4D. I hate that darkening issue.

For reference, this is how normal light levels look.
