Fix for "The page at https://*.sharepoint.com/* ran insecure content from http://{3rdparty_json_api_call}" error in a NAPA app
If you are receiving data through a JSONP API call from a third party service in your SharePoint 2013 NAPA app and you get an error of this pattern - " The page at https://*.sharepoint.com/* ran insecure content from http://{3rdparty_json_api_call} " ... make the JSONP API call from its equivalent HTTPS URL i.e. replace http with https. This fix will work provided the third party API supports HTTPS.
