[Patch] convert darcs logs

[Michael Klier]

Hi everyone,

I've made a small patch to the convert_log.py script to also support
conversion of darcs [1] logs.

The logs should be generated using:

$> darcs changes --summary --reverse

It should be noted that the logs should be retrieved from a master
repository. If you for example clone a darcs repo using the --partial
option the log will not contain all necessary information, like
filenames, from earlier stages of the history.

I've tested the patch on two projects, DokuWiki [2] and darcs itself.
You can see the results on vimeo (if used ffmpeg and didn't play
around that much, so the quality isn't as good as it could be):

http://vimeo.com/3281167

Keep up the good work and best regards,
Michael

PS.: I've attached the patch inline, if you want me to send it via
mail just let me know.
