* Venstar: Add runtimes and battery sensors
* Address review - replace classes with lambda functions
* Clean up patch usage, make temperature_unit it's own function
* Remove double define of entities
As of version 0.14, the venstar_colortouch lib always initializes hum_setpoint to None. When a thermostat actually reports a humidifier state, this value is replaced with the integer value of the setpoint. This changeset corrects the humidifier detection as well as adds basic test cases for the Venstar component.
