v2:
* Change -load to -spinner
* Replace with ternary conditional
* Replace return with throw error
* Change error to no_response
* Delete -webkit, slow spinner down

v3:
* Changed how get_json() returns data

v4:
* Added try catch to work with throw error
* Catch in case of error doesn't terminate fetching other results,
  but keeps downloading

v5:
* Spinner in queue and other parts of website
  had the same class name, which made it look weird.
  Changed queue specific class name to "queue-spinner"
* Fixed indentation
