Bug 2067 - Clean up dev.eclipse.org

This patch also wraps the Eclipse Infra status page with the solstice
theme. I am keeping committers/css, committers/html and committers/js
since this template is currently being used on more than 20 pages. I
needed to include committers/menu/menu.php since it's currently being
used on the same page of this old template.
