vzubc: distinguish between two importance levels

function important() (which is currently only used for quiet mode)
now returns
	0 in "not important" case,
	1 in "maybe important" case, and
	2 in "important" case.

This will be used to colorize the output.

While at it, fix passing failcnt to the function.
