Need to delete old releases of Roller from Apache Dist

[Glen Mazza]

Hi Dave, in case you missed this one due to all of my JIRA closures 
yesterday:
https://issues.apache.org/jira/browse/ROL-1989
We need you to go in and delete the old 5.0, 5.0.1, 5.0.2 folders from 
dist--it's really quick, I'd happily do it but I don't have the file 
permissions.  Forget about the svnpubsub issue, we can look into that later.

Regards,
Glen
