site-maven-plugin should add nav links to mvn site in README.md-based index page

[Pr0methean]

At https://pr0methean.github.io/BetterRandom/ there are no links to any of the pages generated by mvn site, such as the dependency report or the Javadocs (for which I've added the necessary plugin to the pom.xml). Why can't the plugin add those in a sidebar of the index page, when the rest of the index page is just a render of the README.md? (Of course, to keep in sync with the rest of the repo, this will mean executing mvn site server-side whenever the site is a few hours and a push old.)
