pom updated:
1. copy runtime dependencies to the module lib directories with maven-dependency-plugin
2. added properties for dependency/plugin versions
3. added maven-javadoc-plugin to reporting
added .gitignore file to archetype
Added ExampleUnitTest.java from vertx-gradle-template
deleted site.xml, it was causing the site/index.html file to generate with an empty navcolumn
modified archetype-metadata.xml so src/site/images are not filtered which was making them unreadable.
