PCL and PrimaGIS Feeds and Stats

This past weekend I connected the PCL and ZCO/PrimaGIS repositories to CIA, the open source notification system used by the MapServer project. Stats and Feeds about revisions to our repos are now online: PCL, ZCO and PrimaGIS. I also hacked Micah Dowty's ciabot_svn.py into a reactor for our Roundup tracker so that messages about new or changed issues are also echoed to CIA: Issue Tracker.
