gitweb: plug followlines UI in filerevision view

Mostly copy CSS rules from style-paper.css into style-gitweb.css. The only
modification is addition of !important on "background-color" rule for
"pre.sourcelines > span.followlines-selected" selector as the background color
is otherwise overriden by "pre.sourcelines.stripes > :nth-child(4n+4)" rule.
