Added function "colored()" that prints text with a color that is passed in. Converted many calls to "print" to being calls to "print colored". The prompt, the header, and the help output are the 3 types of colorized output, and each has its own color. Colorization is done through Term::ANSIColor, which is included with modern versions of perl. This is optional, and should not need to be present if color.interactive is not turned on.
