Ton Plomp contributed a patch in June 2010 to resolve a bug whereby
automatic additions of changesets were not working. Another bug with
incorrect timezone offsets was also resolved. Finally, Ton's patch also
allows for the author email address to be unspecified on a commit.

In October 2010 Marcel Bennett reviewed Ton's patch and made a few minor
changes/corrections. Marcel has also added the ability for the
SourceHgWeb plugin to retrieve a list of files modified in a commit.

I have modified the patch to escape variables before outputting them so
that this plugin is safe from potential XSS vulnerabilities.
