[css3-multicol] Minor/editorial: color definition in column-rule

The current column-rule value syntax is:

<'column-rule-width'> || <'column-rule-style'> || [ <'column-rule-color'> | transparent ]

I was wondering about the need for the transparent option in the third grouping; it turns out
this is due to css3-multicol referring to css21's definition of the <color> type. Given that
CSS3 Color is a REC I'd rather refer to that if it's easy to do at this point.
