Ordering of git tags is wrong

[ascheman]

Tags in HTML or MD (or even other formats) should be ordered by commit dates. Tags belong to commits and thereby form a timely ordering of commits. For some reason, the ordering of the tags is not used when generating a git log report. Instead, tags seem to appear in a lexicographical ordering. Hence the output does not reflect the order of changes by time, cf. https://dev.dukecon.org/nexus/content/sites/site/org.dukecon/dukecon-server-api/1.3-SNAPSHOT/dukecon-server-api/gitlog.html
