[PATCH 3/9] gitweb: Refactor printing shortened title in git_shortlog_body and git_tags_body

[Jakub Narebski <jnareb@gmail.com>]

Separate printing of perhaps shortened title (subject) in
git_shortlog_body and git_tags_body into format_subject_html.

While at it, remove presentation element <b>...</b> used to format
title (subject) and move formatting to CSS.
