commit 6a8749d3bd1570faa3dc07e80efc8fcef5953aa0
parent 8a3685bcf2612206fc24a2421acb53dd83aeab85

Add commitdiff between commit and each of it's parent

A link is added next to each parent of a commit, leading to the new
diff-functionality in ui-diff.c.

Also added support for a path-parameter to filelevel diffs accessed via the
diffstat.
