[PATCH v4 16/16] md2html: change css name to not conflict with highlight

[Andy Green]

md2html gets pygments to define the css for "highlight", making display
of the blame view fragile against pygments version.  On Fedora 28 /
python3-pygments-2.2.0-10.fc28.noarch, "highlight" gets redefined so
it no longer displays at the top of its parent.

This patch changes the css class name used by md2html to "md2html_highlight"
so there is no conflict with other definitions of "highlight".
