this adds the new elastic-recheck-unclassified report, which generates an html page of all the unclassified gate failures. it also runs this command, and the elastic-recheck-graph command not only on cron, but also on updates to the repository. In order to do this safely, we create a new er_safe_run.sh in /usr/local that provides a flock front end to ensure we won't race on our html writes.
