Before we rsync new content from the job's workspace to www.qa or download.jboss.org, we should compare the previous build's git revision(s) to decide if the new build needs to be published.

May want to add an override flag in the job to FORCE a publish (ie., a manually built aggregate).

Sample files to check:
