* Implement supported_features for the climate component
* Test supported features
* Convert generic thermostat to supported features
* Max / min temperature are not features
* Fix lint
* Min / max humidity are not features
* Linting
* Remove current temperature / humidity
* Move c-hacker-style constants to boring integers. Booo!
* Refactor all the climate platforms to use the new supported_features
* Force all climate platforms to implement supported_features
* Fix mistakes
* Adapt hive platform
* Move flags into a constant
* Calm the hound
This lets components declare their precision for temperatures. If
nothing is declared, we assume 0.1 C and whole integer precision in
F. Currently this supports only WHOLE, HALVES, and TENTHS for
precision, but adding other precision levels is pretty straight
forward.
This also uses proliphix as an example of changing the precision for a
platform.
Closes bug #4350
* Separate platform and presentation units in climate
* Fix unit tests
Maybe
* Fix unit tests some more
Maybe
* Rename _platform_unit_of_measurement to temperature_unit
* Fix tests for renamed attribute
