Display Configured And Available Queues And Workers
Add view for configured and available queues and workers.
These additions will provide an overview of the current configuration.
The queues overview can display registered queues with number of working jobs.
The workers overview can display running workers and their registered queues.
Right now, it's only possible to see active processes (failed, running, and waiting jobs) and the schedule.
ResqueInstance#running is an example of worker introspection, and it may be useful for the workers overview.
The "running" view may be a good place for a consolidated workers and queues overview.

Yeah, we could change "Running" to just "Workers" and either show 'em all like resque-web does, or sort the running ones at the top.
