added red color to misses and a flag to turn this on (off by default)

Added ANSI Color to misses and a flag to turn this on. I know this is a larger task than what I have done, but thought it would be good to push this now and get some feedback before I go whole hog into it. Right now it paints the whole miss line red if you have it turned on. I want to add support for partial line coloring and add support for lines that are not tested but don't need to be (struct declarations and the like).
