fixing links
removed outdated dep in dependencyManagement of the root pom.
Moving the java code translations to the jar they're being used from.
Added justification as a required attribute for ignored differences.
Some small corrections on the site.
Fixing maven plugin itest failure.
Completely reworked site generation. It now includes the maven plugin
site and is generated right from the parent pom. No need for specialized
sub module. Also the javadocs are split per module, but work is needed
to correctly link between them.
