6.0.1
- improved the MAVEN plugin to hide content of potentially sensitive properties from printing into Maven log (issue #2)
- added --z option ('compareDestination' in MAVEN and ANT) to check content of existing result file and to not replace it if content equals (issue #1), by default turned off because makes some overhead

- improved tests
- minor bug-fixing
