Title: Support for class specific queue limit, garbage, priority settings

This pull request supports class specific settings for Backburner::Worker::ThreadsOnFork as follows:
```Ruby
class SuperJob
include Backburner::Queue
queue "super-job:5:1000:10"
end
```
the queue super-job will have 5 threads, 1000 garbage limit and 10 retries limit

```Ruby
class SuperJob
include Backburner::Queue
queue "super-job"
queue_jobs_limit 2
queue_garbage_limit 500
queue_priority 6
end
```
the queue super-job will have 2 threads, 500 garbage limit and 6 retires limit.

Note: class specific settings (if not nil) override name specific settings.
