* colour *

This command toggles colour on and off. The colour itself is controlled by
embedded tags in text strings which all begin with a '~', eg /~FG.
They are the following...

Control tags...

  /~RS : Rest terminal to default state
  /~RV : ~RVReverse video
  /~OL : ~OLBold
  /~LI : ~LIBlink/flash text. This only works on some terminals, others may
        ~LIsimply display it as bold.
  /~UL : ~ULUnderline text. As with blink this doesn't work on all terminals,
	    ~ULsome just display it as bold.

Foreground colour tags...

  /~FK : Foreground black
  /~FM : ~FMMagenta/purple
  /~FR : ~FRRed
  /~FY : ~FYYellow/orange
  /~FG : ~FGGreen
  /~FB : ~FBBlue
  /~FT : ~FTTurquoise/bright blue
  /~FW : White

Background colour tags...

  /~BK : Background black
  /~BM : ~BMMagenta/purple
  /~BR : ~BRRed
  /~BY : ~BYYellow/orange
  /~BG : ~BGGreen
  /~BB : ~BBBlue
  /~BT : ~BTTurquoise/bright blue
  /~BW : White

So this: "/~FG/~BB/~LIhello world" would produce ~FG~BB~LIhello world

To display the colour tags as themselves without them producing a colour
prepend the ~ with a / , eg //~FG
