3. style: Implement basic column spans. …

   This patch provides some of the groundwork for column spans greater than
   1. It implements the column-span CSS property (prefixed so as not to be
   exposed to content) as well as the corresponding colspan attribute;
   although the former is not well-specified outside of CSS multi-column
   layout, INTRINSIC refers to it. Although width is distributed to
   spanning columns, they do not yet contribute minimum and preferred
   widths; this will be implemented in a follow-up.
   
   Additionally, this patch cleans up some miscellaneous formatting issues
   and improves the handling of table rowgroups.
