[Building Sakai] Snapshot repo cleanup

[David Horwitz]

Hi All,

With the move of 2.9 and later artefacts to the sonotype repo there 
where a lot of stale artefacts in the snapshot repo at:

http://source.sakaiproject.org/maven2-snapshots/org/sakaiproject/

As a result we where getting some problems with build pulling in these 
artefacts. As a result we have cleaned up this folder. Jenkins is busy 
rebuilding a whole bunch of 2.8.x and contrib projects that should 
repopulate the repo with current projects. If you build depends on an 
artefact thats no longer there please let me know.

Regards

David
