v5.3.0

• Added ability to specify which queue channel each job (webhooks, scripttags, and after_authenticate) should use (with a default of null) (#177)
• Cleaned up AuthShop middleware to check for any existence of the response being based upon Symfony response (in case someone is using a custom response)

No upgrading is needed however if you wish to use the new queue config, please refer to the Upgrading doc in the wiki for what entries to add to your config/shopify-app.php file.
