Use whole degrees fahrenheit for thermostats

Browse Source 
Users of fahrenheit generally expect to see whole degrees. The fahreneit

scale is suffiently precise that decimals aren't really useful in terms

of temperatures humans care about.



This change rounds fahrenheit values to whole degrees and celsius values

to one decimal place. It also renames the ThermostatDevice._convert()

method to _convert_for_display(), making its purpose more clear. It is

not useful for the min_temp() and max_temp() methods, as those relate to

the internal state of the ThermostatDevice object, and may use different

units. Adding optional source and target units to _convert() would have

added needless complexity, it's cleaner to just use convert() in those

methods.
