registry: SecurityPanelController with Arm.Response and its errors

Alexa.SecurityPanelController is described from its page: version 3 (the stub of 1.5.2 said 1), armState and the
four alarms, Arm and Disarm. ctx.respond() answers Arm with Arm.Response under the namespace of the interface,
its payload checked (exitDelayInSeconds 0 to 255, bypassedEndpoints), and Disarm with a Response. A Disarm
carries the PIN the user said when the panel is declared with supportedAuthorizationTypes; the handler checks
it and answers UNAUTHORIZED, which goes under Alexa.SecurityPanelController like the five other error types.

A panel declared without options lists armState, where 1.5.2 listed no property; alarms are declared.
17 examples of the two pages are saved as fixtures. 215 tests pass, 207 before.
