Make ignored/skipped different from changed

Since a skipped/ignored action is _very_ different from actual changes to a system, it always bothered me that  it was not easily distinguishable when skimming the output. This change makes ignore/skip a different color, and I chose cyan. Contemplated using dark-gray/blue, but prefered something that is readable with most terminal colors.
