Get bus / queue details through the rest API

For getting the status of the queue, memory usage, and statistics something like 'GET /queues/myqueue' or similar would be helpful.

Definitely something I would like to take a look at. Right now the default queue names are MD5 hashes of the handler type names in order to ensure uniqueness and persistence across restarts, which isn't intuitive or discoverable. I'm going to have to rethink that so that the queue names are a little more user friendly and can survive a type rename -- possibly with a [Queue] attribute or some such. Once that's in place then we will have much friendlier queue names that would make such an API much more useful.
