It would be helpful if a binary could tell which version of the source it was built from, at least if it's a tagged release.

com.hp.mw.source ant property is already injected into the .properties files in the .jars. However, it's not set and does not cascade down properly from the top level build script anyhow, due to the use of the runant macro.

1) Change the build.xml script so the property is utilized correctly, then change the build-release-packages.xml so a value is set based on the svn tag.
2) Change e.g. TransactionManagerService so it uses Configuration.getBuildTimeProperty to get and print the value in the logs at AS startup.
