SCI/SCUMMVM: Added an option to enable the dithering removal algorithm (so called "undithering") in the graphics options tab. The algorithm is now disabled by default, after popular demand. In retrospect, we really shouldn't have made it default, in order to preserve the authenticity of the graphics in early SCI EGA games, and allow the user to opt in and enable the option if needed. Unfortunately, the lack of an easy way to modify the option made it hard to do so.
