Removed changes-plugin since it broke maven site-generation.
Merge remote-tracking branch 'upstream/master'
Replaced commons2 with commons-lang3. commons2 is not available in central anymore.
Included Findbugs plugin as a new report.
Included JavaNCSS plugin as a new report.
Removed JavaNCSS plugin again since it breaks the build when using the diamond operator.
Removed site-plugin from POM. Instead the site-plugin from the parent-POM should be used. The configuration was broken anyway since there was a template-file missing.
Added JavaDoc-plugin for site generation.
Let Cobertura create a XML-report.
JavaDoc generation should not let the build fail if there are any errors.
On Java 8 DocLint should be disabled (see also: http://stackoverflow.com/questions/15886209/maven-is-not-working-in-java-8-when-javadoc-tags-are-incomplete)
Removed profile to disable DocLint on Java 8 again, since the other reports were not generated anymore.
Included a first draft of a checkstyle-configuration-file.
