registry: ThermostatController 3.2 and ThermostatController.Schedule

The thermostat is described from its page: one, two or three setpoints with holdUntil, AdjustTargetTemperature,
SetThermostatMode with the six modes (EM_HEAT is new), ResumeSchedule, adaptiveRecoveryStatus, and its seven error
types under Alexa.ThermostatController. A declaration gives supportedModes, supportsScheduling and the properties
the device has; without them discovery is what 1.5.2 sent: HEAT, COOL, AUTO, OFF and the three setpoints with
thermostatMode. supportedModes without HEAT or COOL is refused where it is declared.

ThermostatController.Schedule replaces its stub. Wire change for a 1.x declaration of it: version 3.2 (was 1) and
scheduleEnabled listed (was nothing). SetAdaptiveRecovery is taken only with supportsAdaptiveRecovery.

24 examples of three pages are saved as fixtures; the page folds the SetWeeklySchedule example away, its payload
is tested from the tables. 207 tests pass, 191 before.
