Description of the new feature/enhancement

I'm not sure if this has been requested before (I couldn't find it), but I think it would be nice to have the option in the settings to display error output (stderr) in a different color/style than normal output (stdout). For example, this would make it possible to automatically print make the text in std::cerr << "This is an error\n"; red.

I'm not sure how difficult this would be to realize, because normally GetStdHandle(STD_OUTPUT_HANDLE) and GetStdHandle(STD_ERROR_HANDLE) point to the same device. I'm also not sure how this would impact ANSI escape codes being sent to either stream affecting the other or not.

Additionally, this may impact the ability to invoke SetConsoleTextAttribute for the two handles separately, like e.g. this person tried to do.
