[PATCH/RFC] More colors for pretty format: yellow, purple, cyan, white and black

["Tom ten Thij" <mail@tomtenthij.nl>]

Add support for other colors in pretty format the same way %Cred
works. I reordered the if
statements to start with the reset case and order the others by ansi
color code. Not sure if
I have to edit other files or how to do testing for a complete patch.
