2.15.0

Added

• Add DeviceType.HOME_CONTROL_ACCESS_POINT_TWO, mapped to the existing HomeControlAccessPoint class. Fixes repeated 'HOME_CONTROL_ACCESS_POINT_TWO' isn't a valid option for class 'DeviceType' warnings for installations using the Access Point 2 (HmIP-HAP2). Thanks to @krueli for contributing this.
• Add DeviceType.WALL_MOUNTED_GLASS_THERMOSTAT_CARBON and a WallMountedThermostatWithCarbon class for the HmIP-WGTC. The device type was missing, so the thermostat fell back to BaseDevice and exposed none of its readings on the device, even though its WALL_MOUNTED_THERMOSTAT_WITH_CARBON_CHANNEL was already supported. carbonDioxideConcentration, actualTemperature, humidity, setPointTemperature, vaporAmount and temperatureOffset are now read from that channel (fixes #674). Thanks to @Stefan221188 for the diagnostics that made this diagnosable without the hardware.
