The signin form was missing a hidden field for the response_mode parameter. Added it to allow caller to specify a response mode.
Also, made the addition conditional to match the SPEC which indicates to only include the parameter if it varies from the default. If the response_mode is not supplied to the signin form, it is not added to the authorization details.
