* Update Homekit climate.py to remap current mode
This update changes the mapping of Homekit's Current Mode Heating/Cooling State to show the HASS Hvac_action attribute as "idle" instead of "off" when the returned value is 0.
* Update climate.py
removed imported constant no longer being used (CURRENT_HVAC_OFF)
* corrected update to climate.py
trying again to remove unused constant.
* Update test_climate.py
* removed "change" comment
The added comment describing the change was not needed and should not be included, as it will already be described via "git annotate" (per @jc2k)
