Disable Validator Option in Swagger object

[cyrilj9696]

Hello,
Could you please add an option to disable the validator url. As my Tornado application and schema looks fine and i get all the endpoints displayed in the UI but i get this weird error at the bottom maybe cause I'm not hosting any of the schema's.

Clicking on the invalid warning, gives an error like this
{"schemaValidationMessages":[{"level":"error","message":"Can't read from file http://xx.xx.xx.xx/api/doc/swagger.json"}]}

Currently i'm bypassing this error by adding the validatorUrl: null in the swagger object of doc.html, by following this thread swagger-api/swagger-ui#2796

Thanks
