Add option to filter jobs/queues by state

[tomgrossman]

In the main view, you can see the beautiful state graphs, and below the list of all queues.
It would be great to click on a state on a graph, failed for example, and it would filter the list of all queues to only the ones with at least one failed job.

It should be possible by iterating all of the queues, and search for at least one failed using the getJobs('failed') bull method.
