Breaking changes

lights now use Kelvin rather than mired for colour temperature. This will affect configuration files that are maintained outside of the repository. #1086
The following lights may now have the color temperature inverted, as it was not clear whether the previous lack of inversion was a bug or intentional:
- Atomi Ceiling fan
- RGBCW Lightbulb2
- Tampa LED system
- Windcalm fan with light
the color temperature range of lights can now be configured. Lights where the original report or other information indicated the range were updated to the actual range. Others were updated to the common range of 2700K - 6500K. Previously, the Home Assistant default of 153-500 mireds (2000-6500K) was used, so automations that used the full range may need updating to the new range. Mostly this will be unnoticeable in the UI.
