csi: wip: styled underlines

Browse source 
This is work in progress, and fairly untested.

This adds initial tracking of styled underlines. Setting attributes
seems to work (both color and underline style). Grid reflow has *not*
been tested.

When rendering, style is currently ignored (all styles are rendered as
a plain, legacy underline).

Color however, *is* applied.
