Queue state verbose, fixes #4058

Improvement to the Batch Queue:
- Start Queue/Stop Queue checkboxes replaced with one swith.
- It is now immediately clear whether the queue is running or not.
- The queue is visually stopped once it is empty.
- String keys fixed to use BATCHQUEUE_ prefix instead of FILEBROWSER_.
