[JBoss-dev] JBoss 4.0.x thirdparty dependencies

I changed Branch_4_0 build-thirdparty.xml to point to javassist 3.2.0.GA (from CR2) and removed the explicit reference to jbossretro, since only the jbossretro-rt is needed in the jbossas build. Also switched the imported dependency in jbossws14 from jbossretro to jbossretro-rt. I believe, somebody using jbossws14 is interested in importing/checking the implicit runtime dependency for using this package. Finally, what's the purpose of having jboss-aop 1.5.1.snapshot and not just aop "snapshot"? A snapshot is the latest development release of a branch (or HEAD) so isn't 1.5.1 the actual HEAD for aop?
