Hudson Becomes Jenkins

I've upgraded the Hudson instance I use to compile most of my software to the newest version which, after a dispute with Oracle, is now called Jenkins. As well as upgrading the software I've changed the URL to match. I'm using J2EP in order to rewrite the old URLs to their new forms so hopefully all existing links will continue to work as before, but if you spot anything that doesn't seem to work properly please leave a comment so I can fix things.
