[Maven-plugins-developer] Cleaning up repository at http://maven-plugins.sourceforge.net/repository/

[Carlos S. <ca...@ap...>]

This repo should have only the maven-plugins groupId, other groupIds
artifact should go through the usual ibiblio upload process.

I'm removing everything but maven-plugins groupId (they'll be still
available from ibiblio), but I noticed that there're two dirs owned by
ludovicc that can't be removed.
