- made the menu dim darker and a bit more opaque.

The recent localization work has made it apparent that on many images the menu was extremely hard to read because its colors often clash with the background.
The choice of a bright overlay color with extremely low opacity is simply not enough to make the menus comfortable to navigate. Chex Quest was particularly bad but the problem existed in many Doom mods as well.
This also changes the CQ dim color to something a bit more green to better fit with the theme.
