Adding envers support (contribution from Victor Tatai)
Ignore IntelliJ project files
Rename envers property to hibernate.export.envers
Variable "envers" should not be put into hibernate.properties

"hibernate.exoprt.envers" is no Hibernate-Configuration-Parameter.
Hence, it should not be put into the hibernate.properties-file.
Improved log-messages
No configuration for hibernate.dialect might be a valid configuration too
Reverted to old behaviour: export is skipped, when maven.test.skip=true
maven-site-plugin auf Version 3.3 aktualisiert
Reworked APT-Documentation: page-titles were missing
Project-Documentation now uses the own skin juplo-skin
The plugin now scans for annotated classes in dependencies too
Added @since-Annotation to configuration-parameters
Added missing documentation for skip-configuration
[maven-release-plugin] prepare release hibernate4-maven-plugin-1.0.3
[maven-release-plugin] prepare for next development iteration
Offer explicit disable option

Use an explicit disable property, but still default it to test state
Use more descriptive filename for schema md5
Check that md5 path is file and has content
Make output file handling more robust

* Ensure output file directory path exists
* Anchor relative paths in build directory
Text cleanup, spelling, etc.
