[jboss-dev] pom.xml housekeeping

My obligatory pastime those days is to reduce the entropy of the jboss universe by messing up with people's poms. I just spotted that the various ejb3 subprojects used different snapshots of their own ejb3-parent pom! Some used 0.13-1-SNAPSHOT, others 0.13-3-SNAPSHOT, so I moved them to the latest. Sure maven sucks, but can you also do your own housekeeping, please? /D
