This reverts commit eb6e816.
This is in response to a security vulnerability: https://support.cloud.engineyard.com/entries/22915701-january-14-2013-security-vulnerabilities-httparty-extlib-crack-nori-update-these-gems-immediately
Since Zendesk's API validations and error cases are no documented, it is possible that the support app's validations let invalid requests slip through. This means that it's not possible to raise a ticket from the user's request. Prior to this change, such cases would generate a standard Rails 500 error. After this change, the user sees a much clearer error message and receives a text representation of the ticket that was going to be raised, in case they would like to review it or forward it on via email.
