Adjust colors for red-green color vision deficiency

You can adjust colors if you have red-green color vision deficiency. In this case, code fragments such as errors that are usually highlighted in red or strings that are usually green, will change the color to accommodate your needs (red will change to orange, green will change to blue). The color of the progress bar in the test runner will also get adjusted so it can be easily recognized.
