Changed VersionInfo message default to provide more information.

Added a unit test to warn when there is a mismatch between pom version
and VersionInfo version.
Maven releases appear to work as expected, however intermediate
snapshots might not provide a meaningful version. Changed the default 
to be the same as the maven pom version; if no pom file can be found,
fail the test - it is neither a maven build, nor a release.
