[Cooker] mdkonline

[Vincent Panel]

mdkonline/mdkapplet has seen some big changes since 2008.0 and I
couldn't find it in the release notes. So I've added these changes in
the notes here : http://wiki.mandriva.com/en/2008.1_Notes#mdkonline .
If there's something I've missed, feel free to add it. It's also
written in a hurry in poor english and should probably be reviewed as
well.
