Add status page to navigation bar

We have added a status page to the project. This should be added to the
navigation bar to make it more visible. Rather than adding more entries
that will make the bar cluttered, remove the link to the community page
as this only points to the mailing list at the moment and highlighting
that doesn't seem to be resulting in people signing up.
