Clusters dashboard

Totally work in progress, but at least applies now (after lying dormant for 3 months). Not sure if it even works, to be confirmed... I also need to do a massive rebase to make sure it looks like I know what I'm doing. Use at your own risk.


And you did get the top level menu? Btw, this particular hunk does *not* apply cleanly. There's another patch in the package, that modifies its context. That might be the issue.
