Allow emulated hue to set climate component temperature

[chilicheech]

Description:

This enables the emulated_hue component to set the temperature of climate devices.

The goal here is not to have the thermostat show up as a thermostat in Alexa, because with emulated hue it will show up as a light. The goal is simply to be able to say “Alexa, set the heater to 66” and have it set the thermostat temperature in that way. Things like “Alexa, raise the temperature” or “Alexa, I’m cold” or “Alexa, turn on the heater” won’t work. Only specifically setting the temperature will work.

This change makes it do the same thing it does for setting media player volume. The emulated_hue will “pretend” the thermostat is a light and use the brightness level as the temperature for the thermostat. This is the same thing it already does to media players. It uses the brightness level as the volume level.

If you can fix the conflicts that have emerged, I think this is good.
